William Alexander Bridgen (1784–1851): Family Circumstances and Estate Disputes

Research record prepared 15 October 2026. Subject: William Alexander Bridgen senior, Audit Office clerk, husband of Mary Bailey and subsequently Mary Anne Cooper. His son of the same name was born in 1850 and is a separate person.

Scope and evidence

This account brings together my latest research summary, the recoverable portion of the conversation Test successful response, earlier saved research notes, William Alexander Bridgen's registered will, William Watt's registered will, William Bridgen's death-entry image, and the National Archives catalogue descriptions of the Chancery proceedings. It preserves the newer identification of William as the man born in 1784, while recording the conflicting ages rather than altering them to fit that identification.

The original conversation retrieval returned only its last five exchanges, without its uploaded attachments or a route to earlier messages. Relevant local copies of the two wills and the death-entry image were found and inspected. Earlier local notes supply additional citations, but some predate the discoveries in John's present request. Consequently, this is a substantial research synthesis with explicit citation gaps, rather than a claim that every earlier upload has been recovered.

Evidence is described as follows:

• Primary record checked: the relevant scan or live catalogue description was inspected for this account. A catalogue establishes what the catalogue says; it does not substitute for the underlying pleading.
• Earlier research: a detail carried forward from a saved research note or the recovered conversation, with its surviving reference. The original image was not necessarily rechecked here.
• Reported finding: a discovery supplied in John's present instructions whose underlying image or complete citation was unavailable for this account.
• Hypothesis: an interpretation requiring further evidence.

Bracketed source labels refer to the source register below. Uncertain names and amounts are identified as uncertain. No continuous diplomatic transcription of either will is claimed.

Parents, baptism and siblings

The current family reconstruction identifies William's parents as John Bridgen and Marianne Watt, married in 1783, with William baptised in 1784. These are the latest reported findings and form the basis of the title. The precise marriage and baptism dates, churches, register references and image identifiers have not survived in the accessible material and must be added from the original records. A baptism in 1784 does not alone establish a birth in that same year unless a birth date is also recorded. [R1]

This identification fits two independently preserved details: William's 1850 marriage record names his father as John Bridgen, deceased, and the 1851 census gives his birthplace as St Marylebone. It also gives a family explanation for the relationship to William Watt, who expressly calls William Alexander Bridgen his nephew in his will. [R2, P1]

The earlier research had already found a John and Marianne/Marienne Bridgen family in St Marylebone, although it had not yet found William's baptism:

The John and Harriett entries support the sibling group if the 1784 baptism identifies the same parental couple. They should be checked together in the register, including any abode or occupational details. No further siblings are named here without a surviving reference. [R3]

Harriett Bridgen and Harriet Thomson

William's 1851 will provides £20 a year for the life of Harriet Thomson, payable from the property proceeds, with quarterly payments through Mr Willoughby Lawrence. This is a specific continuing financial provision. [P2]

The possible identification of this annuitant with Harriett Bridgen, baptised in 1791, is attractive now that the John and Marianne family has become central to the reconstruction. It remains a hypothesis. The will clause inspected does not call Harriet his sister, and the earlier London marriage searches had not established a Bridgen-to-Thomson marriage. A marriage, probate record or other document connecting the names is still needed. [R3, P2]

An older research lead involving John Philip Thomson v Harriet Thompson, divorce file J 77/146/3264, was discarded after the woman was identified as Harriet née Statham. It must not be revived as evidence for William's annuitant. [R3]

The birth-year problem

The records contain a material disagreement about William's age:

The 1841 age is preserved in the earlier evidence register. The 1851 age appears consistently in the saved biography and research notes. The death-entry age of 68 was checked against the supplied image for this account. [R2, R3, P3]

The older research treated the 1851 census age as the strongest birth-date anchor and therefore searched around 1794. That led it to regard the 1804 Mary Bailey record as probably belonging to another man. The latest 1784 baptism, the first-wife findings and the older ages require that assessment to be revised. The old conclusion should not be copied forward as though it incorporated the later evidence.

There is not yet evidence explaining why the 1851 census says 57. An enumerator's error, a mistaken household return or an inaccurate reported age are possible. A deliberate ten-year reduction is also conceivable, but no motive or deliberate act has been established. The death entry likewise records an informant's age statement rather than a birth certificate.

The sound approach is to retain each age as written, compare the identities using occupation, addresses, spouse and kin, and attach the 1784 baptism through those links rather than through age alone.

First marriage: Mary Bailey, 1804

The latest research identifies William's first wife as Mary Bailey, with a marriage in 1804. The surviving earlier source reference is a banns record at St Andrew, Holborn, naming William Alexander Bridgen and Mary Bailey: Ancestry collection 1623, record 217164, London Metropolitan Archives reference P69/AND2/A/01/MS 6670/9. [R1, R3]

This distinction in record type needs to remain visible. The earlier notes had found banns but had not found a separate completed marriage entry. John's current instructions describe the 1804 marriage as a finding from the subsequent research. This account adopts Mary Bailey as the current first-wife identification, while leaving the completed marriage entry, exact wedding date and full citation as items to recover. Banns alone establish an intended marriage.

With a birth around 1784, William would have been about twenty in 1804. A birth around 1794 would make him about ten, which was a principal reason the earlier investigation separated the records. The current identification resolves that particular difficulty, provided the baptism and marriage belong to the Audit Office clerk.

The 1841 household

The 1841 census records the household at No. 18 Coleshill Street, St George Hanover Square, Middlesex:

The address has been confirmed as Coleshill Street, matching the 1840 rate-book entry; an earlier reading of Denbigh Street was mistaken. The complete census piece, book, folio and page citation still needs to be captured. [R3]

Mary is the woman now identified as Mary Bailey. Their appearance together in 1841 provides evidence of a household during the first marriage, but does not establish whether they had children. No child of that marriage is securely identified in the material assembled here.

Earlier candidates involving Ann Archer, whom a William Bridgen married at St Pancras on 21 February 1826, should remain separate. Likewise, Amelia Bridgen, baptised at Christ Church, Spitalfields, on 16 April 1843, was found to belong to a William-and-Ann household in which the father was a plasterer. Neither is evidence for this clerk's first family. [R3]

Mary Bailey Bridgen's death and burial, November 1850

The latest reported findings give Mary's death as 12 November 1850, followed by burial on 20 November 1850. The interval between the reported death and burial is eight days. [R1]

These dates explain William's status as a widower when he married Mary Anne Cooper the following month. The second marriage took place 21 days after Mary's death and 13 days after her burial.

The underlying death and burial records were not recovered for this account. Their parish or cemetery, age, abode, register number and any civil-registration reference must therefore remain unfilled. No cause of Mary's death, medical attendant or informant is inferred. Her record must also be kept distinct from the second wife's later records under Bridgen and Rush.

Marriage to Mary Anne Cooper and the birth of their son

William married Mary Anne Cooper on 3 December 1850 at St Margaret's, Westminster. The saved biography preserves the following details from the marriage register: [R2]

The witnesses were William Needham and Mary Pinney. The exact register citation and image identifier remain to be added. The blank paternal field for Mary Anne should be recorded without assigning a reason to it.

Their son, also William Alexander Bridgen, was born on 7 December 1850 at 10 Palace Street, Westminster St Margaret's, four days after the marriage. This birth date and address are preserved in the earlier biography. [R2]

The chronology places Mary's death, William's second marriage and the child's birth within less than a month. It does not itself establish the history of William and Mary Anne's relationship, when they began living together, or what the first wife knew. No allegation about their conduct is warranted from these dates alone.

The 1851 census

On 30 March 1851, the new family was recorded at 9 Denbigh Street, Westminster, in the St George Hanover Square area: [R2, R3]

The address and Audit Office employment connect the census household to William's will. The age of 57 is retained despite the conflict discussed above.

Mary Anne's age also varies across the family research. Later Rush returns and her reported death on 4 February 1910, aged 79, favour a birth around 1830–1831, while the 1851 census implies about 1824–1825. The leading candidate is a Mary Ann born 29 September 1828 and baptised at St Marylebone on 24 June 1830, of Paddington Street, daughter of Eliza Cope Roberts and Daniel Cooper, whose two surnames show they were not married. It is not an established parental identification. [R2]

Death at Margate, 2 October 1851

William's death-entry image records the following: [P3]

“Cephalitis” is the working reading of the second medical term in the scan. The original handwriting should accompany any eventual formal transcription; it should not be silently replaced with a modern diagnosis. The entry gives two durations and states that the causes were certified. It does not name the certifying practitioner in the portion available here.

Edward Best is the informant and is expressly described as present at the death. The entry does not describe him as a doctor or a relative. His residence or connection to 17 Church Square requires separate research. There is no basis here for treating his presence as suspicious.

The family census and will place William in Westminster/Pimlico, while the death entry places him at Margate. The reason for his stay there is unknown. A visit, lodging arrangement or stay connected with illness would each require evidence. The cropped image does not preserve the full registration-district heading or the certificate's ordering information.

His infant son was still under ten months old when he died. William had signed his will 37 days earlier, on 26 August, and probate followed 23 days after his death, on 25 October 1851. The proximity of the will to his death does not establish that he was already suffering from the conditions entered at death.

Uncle William Watt and the earlier estate

The relevant will is William Watt, gentleman of Arnold Place, Francis Street, Walworth, Surrey, National Archives PROB 11/1999/235. The local PDF was inspected for this account. Its execution clause is dated 5 May 1842, and the probate clause records proof on 20 May 1844. Thus “Watt's 1844 will” identifies the probate year; the instrument itself was made in 1842. [P1]

The will expressly identifies William Alexander Bridgen as Watt's nephew. With Marianne Watt now identified as William's mother, the current reconstruction is that Watt was his maternal uncle. The will establishes the nephew relationship; the precise sibling relationship between Marianne and Watt should be documented from their family records. It should not be treated as independently proved merely by the shared surname. [P1, R1]

Provisions connecting the later parties

The will gives William Alexander Bridgen a leasehold property in George Street, Islington, in the parish of St Mary, Islington, and also leasehold messuages/tenements, ground rents and premises at Walworth. The Walworth interest is subject to an apportioned annual ground rent, the covenants of the existing leases, and a life annuity of £20 a year for Watt's sister Jane Scotton, wife of John Scotton. The ground-rent amount is provisionally read as £12 12s and needs confirmation in the full transcription. The annuity is directed to be paid quarterly from the first relevant rent-payment day after Watt's death. [P1]

The clause provides for Jane's separate use and restricts dealings with the annuity. This is relevant to later estate administration because the gift to William carries a continuing payment obligation. It is not simply an unrestricted lump-sum legacy.

The will also contains provisions for the niece identified in the conversation as Elizabeth May Head, including a £20 annual bank annuity, leasehold properties in Amelia Street numbered 24, 25, 26 and 27, with ground rent and lease conditions, and a £400 mortgage interest connected with premises in Ewer Street, Southwark. Her surname and middle name are difficult in the registered hand; “Elizabeth May Head” is retained as the research identification rather than presented as a newly settled diplomatic reading of every occurrence. [P1, R4]

William Alexander Bridgen and this niece share the residue and are appointed executor and executrix. The probate clause names William Alexander Bridgen and Elizabeth, described as a widow, as the proving representatives. This makes William both a beneficiary and a person responsible for administering Watt's estate. [P1]

The will includes other family and mourning gifts. A full transcript should preserve those clauses, including cancellations and interlineations, before expanding the family tree from them. This account concentrates on provisions that bear directly on the Bridgen and Head estate connections.

What the two wills establish together

William's own will names the late William Watt and repeats an annual payment connected with Watt's directions. It also disposes of Walworth leaseholds and ground rents. The two instruments therefore provide a direct documentary connection between the earlier Watt estate and William's financial affairs in 1851. [P1, P2]

The overlap does not establish that every property William owned originated with Watt. Nor should the four Amelia Street houses numbered 24–27 in Watt's provision for Elizabeth be confused with William's later houses numbered 28–29. A property schedule and the original leases are needed to establish which interests passed by which route.

An earlier investigation considered William Watts of John Street, Walworth Common, whose will was proved 7 May 1841, PROB 11, piece 1946, Ancestry record 461966. That was a real separate will, apparently leaving the estate to his wife Sarah. It must not replace PROB 11/1999/235 as the identified uncle's testament. The associated Robert and Ann Barrow material remains a separate lead unless a further document connects it to this estate. [R3]

William Alexander Bridgen's will, 26 August 1851

William's will is National Archives PROB 11/2140/190. It describes him as formerly of No. 2 Robert Street, Chelsea, then of No. 9 Denbigh Street, Pimlico, and of the Audit Office, Somerset House, Middlesex. It was executed 26 August 1851 and proved 25 October 1851. Both pages of the local registered-will copy were inspected. [P2]

The registration pages contain neighbouring testators' material. The earlier text above William's opening and the later will beginning beneath his probate clause are not part of his will.

Wife, son and property

William gives his wife Mary Anne Bridgen, described as formerly Cooper, the benefit of his leasehold property during her natural life, or for as long as his interest in it continues. After her death, the property passes to his son William Alexander Bridgen, subject to the specified payments. The property includes:

• 28 and 29 Amelia Street, Walworth.
• 1, 2 and 3 Church Street, Walworth. Earlier notes suggested “Clenton Street”; the will reads Church Street.
• A small tenement with house, premises and yard, formerly occupied by Mr Perry, in Church Street, Walworth, parish of St Mary, Newington, Surrey.
• Ground rents associated with pieces of ground in Amelia Street.

The will also gives Mary Anne the household furniture, plate, linen, pictures and other personal belongings described in the following clause. [P2]

The leasehold qualification matters. These are interests limited by the underlying leases and their remaining terms. The document does not establish that the same interests survived intact until Mary Anne's death in 1910 or that the son then received a particular amount.

Named charges, debts and financial arrangements

William directs that the sums due should be paid from the life-policy proceeds, the balance of the mortgage money and the bond. If these resources are insufficient, enough of the leasehold property may be disposed of to meet the deficiency, or another course taken by the executor with his wife's consent. [P2]

The estate therefore combines family provision with existing financial commitments. “Sums so due,” the reference to a marriage settlement and the acknowledgement of a pre-existing note are reasons to avoid describing every named payment as a voluntary gift.

Executors, witnesses and probate

Mary Anne is appointed executrix, together with his friend James Lucas, described at a Camberwell address. His complete address is left unresolved here. The probate clause reserves power for the other executor to take a grant later. [P2]

The witnesses are read as Benjamin B. Anthony and Henry East. Probate was granted to Mary Anne Bridgen, widow and relict, on 25 October 1851. This provides a firm link between the will and the widow who later appears as Mary Ann Rush.

People named in William senior's will

These notes were moved from the biography of William Alexander Bridgen junior. They supplement the table of charges above.

Further research should establish whether William senior had older children or other dependants and explain the obligations named in the will. Other targets are Audit Office and Somerset House employment records, earlier census and directory entries, deeds for the Walworth leaseholds, life assurance records, the Watt family, and the marriage settlement papers connected with Mary Anne Jane Briggs.

Mary Ann Jane Lynn → Taylor → Briggs, and Edmund Briggs

The latest research identifies the woman named in William's will through the surname sequence Mary Ann Jane Lynn → Taylor → Briggs. She married George Taylor in 1838 and, after his death, Edmund George Briggs in 1845. Parental details, witnesses and full register references were not present in the recoverable material. [R1]

This sequence is valuable because a search only for a marriage between a Mary Ann Jane Lynn and Edmund Briggs could miss a marriage indexed under Taylor. The settlement named in William's will may clarify which marriage occasioned the arrangement, what property it concerned and why William held or owed the relevant funds.

By 1853, the administration summons identifies Edmund Briggs of the War Office, Whitehall, and his wife Mary Anne Jane Briggs. The uncommon combination of names and her financial role make the identification with William's testamentary payee strong. Her relationship to the Watt family, and the origin of William's obligation to her, still require the settlement and pleadings. [P2, C2]

The Head v Rush catalogue initially calls a defendant George Edmund Briggs, and after revival uses Edmund Briggs. Both are catalogue forms of Edmund George Briggs. [C1]

Earlier research found an older Edmund Briggs of Oranmore/Oramore Terrace, Dalston, whose will dated 11 October 1830 named sons Edmund, Charles and Edward, and a daughter Elizabeth married to Samuel Roper, apparently of the Ordnance Office, Tower. This remains a possible parental or professional connection, without a proved relationship to the War Office defendant. The surviving reference is only to a user-supplied crop, not a complete probate citation. [R3]

Other earlier same-name leads should remain separate: the 1833 Chatham baptism of a Mary Ann Jane Briggs, daughter of James and Ann, does not establish the identity of this adult married woman; a 28 January 1859 death lead and a March-quarter 1859 London registration also require verification before attachment. [R3]

Mary Anne's remarriage to Joseph Rush

The saved biography records the widow's marriage to Joseph Rush on 20 March 1852. Joseph was described as a bachelor and fishmonger, son of John Rush, fishmonger, with a residence in the parish of St John, Westminster. Mary Ann Bridgen was a widow living in Denbigh Street, St Peter, Pimlico. The witnesses were George Lyall and Matilda Rush. [R2]

This marriage explains why the woman who benefited under William Bridgen's will appears in the 1853 cases as Mary Ann Rush, wife of Joseph Rush. The identity is supported by the widowhood, address and sequence of records, rather than merely a matching first name.

Joseph's precise legal or financial interest in the disputed estate should be taken from the pleadings. His inclusion as a defendant does not by itself establish wrongdoing, personal liability for a particular debt, or ownership of his stepson's eventual inheritance.

Elizabeth May Head and Robert Head

The recovered conversation reports that Elizabeth May Head's will was proved on 30 April 1853, and that it names Robert Head as her son and executor. The will's full archival reference, execution date and her exact death date were not recovered. [R4]

This provides a strong explanation for Robert replacing her in the revived Head v Rush proceedings: she had died, and her son and executor was continuing the action. The catalogue independently establishes the replacement plaintiff and the 1853 revival. The probate date places her death before 30 April 1853, but does not establish the date of the revival order. [C1, R4]

The catalogue calls the original plaintiff Elizabeth Ray Head. The conversation identifies her as Elizabeth May Head, connected to William Watt's will. That identification is persuasive within the assembled family and estate network, but the catalogue spelling should be preserved in searches and citations. A comparison of the original bill with her will is still required.

William Watt's appointment of William Bridgen and Elizabeth as estate representatives offers a direct reason why their successors' interests might later appear together in litigation. It does not establish the specific claim each successor made.

The 1853 Chancery proceedings

C 15/36/H10: Head v Rush

Cause number: 1853 H10. Catalogue date: 1853. Record contents described: bill, interrogatories and three answers. The catalogue was checked on 15 October 2026. [C1]

The original plaintiff is catalogued as Elizabeth Ray Head. The original defendants are:

• Joseph Rush and his wife.
• George Edmund Briggs and his wife.
• Thomas Francis Crew.
• John Henry Machu.

The description records an amendment by an order to revive in 1853, with Robert Head as plaintiff. The defendants remain the Rush couple, the Briggs couple, Crew and Machu; the amended entry shortens the Briggs husband's name to Edmund and contains garbled wording for his wife. That catalogue defect must not be converted into a new personal name.

The catalogue explicitly says that details were added from C 32/152, which also contains information about further process. It includes the abbreviation SFP, whose expansion is not supplied here.

• Order-a-copy quotation route

At the access date, the record was undigitised and stored off site, with four working days stated for delivery to Kew. Check current arrangements before planning a visit. No copy has been ordered as part of this account.

C 17/1/411: Sweeting v Head

Catalogue date: 1853. Record type: administration summons concerning the estate of William Watt, late of Arnold Place, Francis Street, Walworth, described as a gentleman. [C2]

The catalogue describes the applicants and plaintiffs as:

• John Sweeting of Middlesex, yeoman, and Jane Sweeting his wife.
• Edmund Briggs of the War Office, Whitehall, Middlesex, and Mary Anne Jane Briggs his wife.

The defendants are Robert Head, Joseph Rush and Mary Ann Rush his wife.

The geographical description in this catalogue says Walworth, Middlesex. Watt's will and its probate catalogue place Walworth in Surrey. Preserve the catalogue wording when quoting or searching, while recognising the discrepancy.

• Catalogue: C 17/1/411, Sweeting v Head
• Request-a-copy quotation route

The catalogue states that this record has not been digitised. The estate named is William Watt's. It should not be relabelled as a suit specifically contesting the validity of William Bridgen's own will without evidence from the summons.

The parties' changing roles

Robert Head is therefore not the plaintiff in both proceedings. The Briggs couple also occupy different sides. This was an explicit correction in the original conversation and is central to understanding the records. [C1, C2, R4]

The changing roles are consistent with competing interests or different requests for estate administration. They do not establish that the defendants committed misconduct. The catalogue descriptions do not disclose the relief sought, the accounts claimed or the eventual decision.

C 32/152: the related cause book

C 32/152 is a Court of Chancery cause book, covering 1852 H 1A–1854 H 191, dated 1852–1854, with former departmental reference Vol. 6. Its catalogue was checked for this account. It is a volume containing many causes, not a third case titled Head v Rush. [C3]

• Catalogue: C 32/152
• Request-a-copy quotation route

The targeted request should identify 1853 H10, Head v Rush, and ask for its entry and continuation references. Those entries may supply dates and procedural references absent from the short pleading description. The explicit catalogue cross-reference links this volume to Head v Rush; no equivalent direct connection to Sweeting v Head has been established here.

Proposed sequence and its limits

John's hypothesis is that Head v Rush came first, with Sweeting v Head following as a competing or responsive application. It fits the change from Elizabeth to Robert Head and the reversal of the Head and Briggs roles. It remains a hypothesis.

The catalogue places Head v Rush in the subseries for pleadings originally filed in 1853, and its cause number is 1853 H10. This supplies more context than the revival notice alone. It still does not give the filing day or establish its position relative to the undated-within-year administration summons. [C1, C2]

The secure sequence is limited to these relationships: Elizabeth's original proceedings preceded the revival naming Robert; Elizabeth died before her will was proved on 30 April 1853; both catalogued legal records concern 1853. The relative order of the two proceedings requires their dated endorsements, filing records or cause-book entries. Neither numerical reference order nor Robert's status as defendant proves it.

The phrase “will dispute” is used here in the broad family-research sense of litigation involving testamentary property and estate obligations. No recovered pleading yet establishes a challenge alleging forgery, incapacity, undue influence or invalid execution of either will.

Where no original citation was available, this account labels the finding as reported rather than independently verified.

[R2] Saved biography of William Alexander Bridgen junior (1850–1920). Local file /Users/jcb/Documents/william-alexander-bridgen-biography.md, also present among earlier Codex outputs. Supplies preserved readings of the 1850 marriage, 1851 census, son's birth and 1852 Rush marriage. This is a secondary research synthesis. Its use of a circa-1794 birth for William senior and its unresolved first-marriage discussion predate the latest findings and are superseded here. No complete original marriage, birth or census citation was preserved in the passages available.

Incomplete original citations to recover

Remaining research tasks

1. Recover the new family records and complete the identity chain. Save the 1783 marriage and 1784 baptism with full citations. Record the names exactly, including whether Alexander appears, then compare John and Marianne's 1789 and 1791 entries. Use the 1850 father entry and Watt's nephew clause to support the linkage; retain the age conflict.

2. Complete the first-marriage evidence. Preserve the 1804 banns and the completed marriage entry if found. Obtain Mary's full death and burial records for 12 and 20 November 1850, including age and address. Check these against the 1841 household. Do not attach children from other William Bridgen families without a direct connection.

3. Finish a controlled transcription of William's will. Resolve Lucas's address, the Briggs stock amount and percentage, and the uncertain bond contact. Keep deletions and insertions visible. Use £20 for Harriet's annuity unless a better image contradicts it; distinguish the Birch note from the direction for its payment.

4. Transcribe Watt's full will and prepare a property schedule. Separate the 1842 execution from 1844 probate. List each gift, lease term, rent and annuity by beneficiary; compare the Walworth and Amelia Street interests with William's later will. Confirm the reading of Elizabeth's full name and the precise family relationship between Marianne and Watt.

5. Obtain C 15/36/H10 and C 17/1/411. Read the original allegations and relief sought, the parties' stated capacities, all filing endorsements, answers and amendments. Record whether the dispute concerns accounts, unpaid legacies, construction of the will, trust property, or another issue. A catalogue description cannot answer that question.

6. Inspect C 32/152 for 1853 H10 and continuations. Extract the original filing date, revival date and subsequent process references. Compare them with the administration summons date before deciding whether Sweeting v Head was a response to Head v Rush.

7. Recover Elizabeth May Head's will and probate reference. Verify Robert's description as son/executor, establish her exact death date and compare the original case papers' name with the catalogue's Elizabeth Ray Head. Follow any further grant or representation needed to account for Watt-estate assets after her death.

8. Document Mary Ann Jane's settlement. Locate the settlement named in William's will. Determine whether William's obligation arose as trustee, debtor, estate representative or another capacity. Test the older Dalston Briggs family connection separately.

9. Identify the remaining estate parties. Establish Jane Sweeting's maiden name and her interest in Watt's estate; determine why Thomas Francis Crew and John Henry Machu were joined. Follow Harriet Thomson, Elizabeth Birch, Willoughby Lawrence, Moore, Cox, Grant and Barton using their stated roles and addresses.

10. Complete the Margate death context. Recover the uncropped certificate and civil index reference; verify the medical wording and registrar's surname. Identify Edward Best and the occupants or proprietor of 17 Church Square in 1851. Look for William's burial and any contemporary death notice, without assuming why he went to Margate.

11. Trace administration after 1851. Look for a later grant to Lucas, estate accounts, property sales and records concerning the infant son's interest. Determine what survived Mary Anne's remarriage and what, if anything, remained at her death. Her life interest and the son's remainder are established testamentary provisions; their eventual financial outcome is still unknown.
