Working Notes
Catherine Kerville — wife identity confirmed (DG-Supp Note 123)
2026-04-18 — DG-Supp Note 123 (pp. 794–796) is the most detailed treatment of Thomas I’s wife. DG gives four reasons supporting “Catharine” (not “Margaret”) as her correct name:
- Tilston pedigrees (Charles II era): The ancient pedigrees DG possessed, written by Tilston, call the wife “Catharine, daughter of Robert Kervile, of Watlington.”
- Kerville of Watlington pedigree: Catherine appears in the Kerville of Watlington pedigree “exactly of the time of Thomas Gurney I.”
- Robert Kerville’s will (d. 1434): Robert Kerville of Watlington mentions his daughter Catharine in his will “but does not mention any daughter named Margaret.”
- No Margaret in Kerville pedigrees: “No Margaret Kervile appears in either of the pedigrees of Kerville of Watlington, or Kerville of Wiggenhall St. Mary’s, of the time of Thomas Gurney I.”
DG concludes: “Therefore my having named the wife of Thomas Gurnay I. Catharine, in the pedigree at page 286, seems correct.”
However, DG notes a complication: The Keswick glass impales Gurney with Kerville without a difference, which “would lead to the idea that she was of the elder branch of the family” — i.e., the main Wiggenhall Kervilles, not the cadet Watlington branch who bore the arms with a difference. Also, “the Jernegans had no fiefs in Castleacre where the inheritance of Margaret lay according to the fine” — suggesting a different Margaret may have existed in a different branch.
Léopold Delisle’s negative: DG reports that “M. Leopold Delisle, in his researches in Norman muniments, has not met with anything which relates to the family of de Capravilla, de Chevreville, or as it is generally written in England, de Kerville, or Carville.” The family was “more distinguished in England than in Normandy.”
DG-Supp Note 123 — Kerville pedigree
2026-04-18 — DG-Supp pp. 796–797 reprints a corrected Kerville of Wiggenhall St. Mary’s pedigree (originally at DG-I p. 389), drawn from the Visitations of 1563 and 1612 and the Islington Court Rolls. The pedigree traces the family from Robert de Capravilla (temp. Stephen) through multiple generations to Thomas Kervyle (d. 1467) and beyond. Key individuals:
- Sir Frederick de Capravilla (temp. Henry III): held two knight’s fees in Wiggenhall.
- Edmund Kervil of Wiggenhall: married Alice, daughter and coheir of Sir John Tilney of Quaplode, Lincolnshire.
- Thomas Kervyle, Esq. (d. 1467): married Margaret, daughter and coheir of Gilbert of the Isle of Ely, Baron of the Exchequer.
The Watlington branch (from which Catherine came) was a cadet with a difference on the arms.
Collateral succession mechanics
2026-04-18 — Thomas I inherited as nephew of Sir John Gurney (d.1408). The HoP biography gives the sequence: Sir John reappointed sheriff 15 November 1408, died 4 December 1408, son Edmund aged 10 died shortly after without issue. Thomas “the nephew” succeeded. This is documented in the DG-Supp Note 121 IPM (already detailed in G23 companion) and confirmed by the Dodsworth collections pedigree (Bodleian Library, vol. 108).
The 1409 Fine Rolls preserve the post-death administrative trace of Sir John’s death directly. On 16 February 1409 the Escheator of Norfolk was ordered to take Sir John’s lands into the King’s hands following his death, the standard escheat-order step opening the inheritance process that the IPM (DG-Supp Note 121) then resolved.[1]
Historical context — Henry V and the Lancastrian zenith
2026-04-18 — Thomas I’s active years (c. 1408–1450) span Henry V’s French campaigns (Agincourt 1415, Treaty of Troyes 1420) and Henry VI’s minority. No record of Thomas in Crown office, Parliament, or military service. The fact sheet correctly notes he appears to have been “a private Norfolk gentleman consolidating a complicated collateral inheritance.”
2026-05-22 update — military service confirmed. The previous “no record … of military service” statement is superseded. Two record sets in the AHRC Soldier in Later Medieval England database, drawn directly from TNA Exchequer Accounts, place Thomas Gournay I in active military service in France:
-
1415 — Agincourt campaign, John Holland’s retinue under Henry V.
- Thomas Gourney, Man-at-Arms, in the retinue of John Holland (1395–1447, then earl of Huntingdon, later duke of Exeter), serving under Henry V. Retinue roll: TNA E101/45/7, m. 1.[2]
- The same individual is mustered as Thomas Gournay, Man-at-Arms, Esquire on 14 July 1415[3] under the same captain. Muster roll: TNA E101/45/18, m. 2.[4]
-
1441 — France expedition, John de Vere’s retinue under Richard of York.
- Thomas of Gourney, Man-at-Arms, in the retinue of John de Vere (1408–1462, earl of Oxford), serving under Richard of York (1411–1460, duke of York). Retinue roll: TNA E101/53/33, m. 1.[5]
Identification. Thomas Gournay I was born c. 1390 (per the fact-sheet timeline), making him approximately 25 at the 1415 muster and approximately 51 at the 1441 muster — both ages consistent with a Man-at-Arms / Esquire serving in the field. The 1415 rank “Esquire” is precisely the rank a Norfolk gentry heir-presumptive would have held while his father Robert (G22) was still living. The Holland affinity in 1415 is consistent with the family’s existing Lancastrian client relationship: John Holland’s mother Elizabeth of Lancaster was John of Gaunt’s daughter, and the Gurneys had been Gaunt clients through Edmund (G23). The Vere–York affinity in 1441 fits the East Anglian gentry military landscape of the period — the de Veres were the leading Essex magnates and recruited heavily from the Norfolk gentry. No other Thomas Gournay/Gurney of comparable rank and East Anglian provenance is known in the period.
Significance. The 1415 Agincourt-campaign retinue place in John Holland’s company puts Thomas I in the most famous English military engagement of the late medieval period, and means the senior Norfolk Gurney line preserved a real military tradition into the Lancastrian zenith. The 1441 service under Vere/York extends that into the next reign and places him in the orbit of the Duke of York at the start of Richard’s first lieutenancy in France — the political ground from which the Wars of the Roses would later grow.
Nine-manor portfolio
2026-04-18 — The existing companion documents Thomas I’s inheritance as approximately nine manors across Norfolk and Suffolk. The IPM of Sir John (DG-Supp Note 121) shows all lands were in feoffees’ hands, complicating the transfer. Whether Thomas I had difficulty establishing his claim to the full portfolio is unknown but plausible — the feoffee mechanism could have created friction with a collateral heir.

Open Questions
- Watlington Kervilles in Blomefield: Does Blomefield have a Watlington entry with Kerville family detail? Would confirm Robert Kerville (d. 1434) and daughter Catherine.
- Keswick glass: Does the Gurney-impales-Kerville glass at Keswick survive? DG says it shows Kerville without difference, suggesting the senior branch. This complicates the Watlington attribution.
- Thomas I’s death date: Not established. He was succeeded by Thomas II (fl. c. 1430–d. 1471). Death c. 1440–1450?
- DG-Supp Note 123 fine between Boking and Thomas Gurnay (p. 385): DG says this fine was “probably” with Thomas II and Margaret Jernegan, not Thomas I, and that Thomas I “was dead before 1444, the date of the fine.” This gives an approximate terminus ante quem.
- Underlying muster rolls TNA E101/45/7, E101/45/18, E101/53/33: Direct pulls of the original rolls would add detail beyond the database index — e.g. the full Latin clauses, neighbouring names in the retinue, and any wage and equipment particulars — but are not required to establish the identification.

Conflicting Information
| Claim | Source A | Source B | Status |
|---|---|---|---|
| Wife’s name | DG-I pedigree p. 286: “Catherine, d. of Robert Kervile of Watlington” | DG-Supp Note 123: Confirmed “Catharine” — four supporting arguments. But Keswick glass shows Kerville without difference (suggesting senior branch) | Catherine Kerville of Watlington is DG’s considered conclusion. The glass complication is noted but doesn’t override. |
Fact Sheet Improvement Notes
- Kerville pedigree context: The Kervilles were a substantial Norman-descended family holding two knight’s fees in Wiggenhall from at least Henry III’s reign. Catherine’s father Robert (d. 1434) is documented in his own will. This is more detail than the current narrative provides.
- Delisle negative: Léopold Delisle finding nothing on the Kervilles in Norman records is a useful scholarly detail — the family was “more distinguished in England than in Normandy.”
- Death date: DG-Supp Note 123 implies Thomas I was dead before 1444 (date of the Boking fine). This could narrow the timeline.
Third military attestation — 1418 Harfleur garrison, under Thomas Beaufort Duke of Exeter
AHRC database entry: “Gournay, Thomas, Man-at-Arms, Garrison; mustered: Harfleur, Captain Thomas Beaufort (c. 1377-1426) earl of Dorset, duke of Exeter, Lieutenant Sir William Willoughby, 1418, Muster rolls, TNA E101/48/6.”[6]
This fills the gap between the 1415 Agincourt-campaign Holland-retinue muster and the 1441 Vere/York France expedition. At Harfleur in 1418 the Duke of Exeter (Henry V’s lieutenant of Normandy) was holding the bridgehead during Henry V’s consolidation phase after Agincourt; service at this garrison station is the natural next phase for the man already mustered at Southampton in July 1415. The Holland-then-Beaufort sequence places Thomas I inside the Lancastrian military client network across two reigns — a continuation of the family’s Gaunt-era patronage chain (Edmund G23 was steward of John of Gaunt’s East Anglian estates 1372-1387; Sir John V served on Gaunt’s 1394 Aquitaine expedition under letters of attorney TNA C61/104 m. 7, already documented in the G23 companion).
1434-35 East Barsham feoffee — third Norfolk attestation
Blomefield’s East Barsham parish entry records that “Thomas Gournay, Esq. and John Hunt, son of William Hunt, of East-Barsham” confirmed Wolterton’s Manor in East Barsham to John Wode in the 13th of Henry VI (1434-35).[7]
This is the third documented attestation for Thomas I, alongside the 1445 Hunstanton seal (Daniel Gurney Supplement Note 126, p. 814) and the 1441 retinue service under John de Vere 13th Earl of Oxford. Together they give Thomas I a documented active-adult span of 1415 (Agincourt) – 1418 (Harfleur) – 1434-35 (East Barsham) – 1441 (Vere/York France) – 1445 (Hunstanton seal). The previous “no record” framing in the G21 companion should be retired.

1440-04-02 East Barsham Woolterton’s confirmation — fourth Norfolk attestation
Mostyn John Armstrong, The History and Antiquities of the County of Norfolk, vol. 5 (Norwich, 1781), Gallow Hundred entry for East Barsham — Woolterton’s Manor: “Thomas Gournay, esq. and John Hunt, son of William Hunt, of East Basham, confirmed to John Wode, of Briston, esq. and his heirs, &c. the manor of East Basham, formerly Roger de Woolterton’s, and John de Bryston, of Bryston, esq. released to John Wode aforesaid, all his right in this manor, April 2, in the 18th of Henry VI. and Catherine, widow of William Hunt, released to him all her right.”
The 2 April 1440 (18 Henry VI) confirmation is the fourth dated active-adult attestation for Thomas I, adding a year between the 1434-35 Blomefield East Barsham entry already in this companion and the 1441 retinue service under the 13th Earl of Oxford. The five-attestation span 1415 – 1418 – 1434-35 – 1440 – 1441 – 1445 (the post-1444 1445 Hunstanton seal probably belongs to Thomas II, per DG-Supp’s “Thomas I probably dead before 1444”). The recurring counter-party in the 1440 and 1447 East Barsham conveyances is the Hunt family — William Hunt’s widow Catherine and her later second husband Robert Mompynson of Wisbich.[8]
