WILLIAM [I] de Tresgoz (-). The 1130 Pipe Roll records "Willo de Tresgoz" in Essex and Norfolk. "…Willielmus Tresgat…" witnessed the undated charter, dated to the reign of King Henry I, under which "Radulfus filius Briani et Emma uxor suus" founded Bresethe Priory in Suffolk
The family of Tregoz (Tresgoz, Treygose) took its name from Trégots, now Troisgots, near St. Lo in the Department of Manche in Normandy. [Anglo-Norman Families, Harl. Soc.CIII, 106.] From the 13th Cent onwards there was a Cornish family who spelt their name in the same ways. If, as the so-called Battle Abbey Roll claimed, the head of the family came over with the Conqueror, there is no evidence in Domesday Book or elsewhere that he acquired any estate in this country.
The first member of the family noted in England was William de Tresgoz who in 1130 held land in Essex and Norfolk [Pipe R. 31 Hen. I ., 60. 95] and was then farming the estates of William Peverel of London (at that time in the king's hands) [Ibid. 135]. He claimed allowances for making two vineyards at Maldon.
Apparently contemporary with William was Robert de Tresgoz who gave land at St. Croix (Calvados) to the Abbey of St. Stephen at Caen when, shortly before his death, he became a monk there; this gift was among those confirmed to the Abbey by Henry II in 1156 [Cal. Doc. France, 160].
From the recurrence of Robert as a forename in the English branches of the family it is likely that he was closely connected with William. However that may be, William was succeeded by Geoffrey (I), Robert (II), John (III), and Philip (IV) Tregoz; the last three were certainly brothers, and all four were probably sons of William.
A charter, however, of William de Braose, made about 1140, giving to the Abbey of St. Florent (the mother house of Sele Priory) the land which Sarazenus held and a house on the north of the church of St Mary (of New Shoreham) is attested, among others, by 'Johannes Gosfridi Tresgot' [Salter, Oxford Charters, 6. Cf. Chartulary of Sele Priory (ed. Salzman), 8]. Dr. Salter, naturally, translated this as 'John' [son of] Geoffrey'; but it is possible that the word omitted by the scribe was 'brother' – Geoffrey heing then head of the clan.
That Geoffrey was the heir of William is shown by the fact that William's lands of the Honor of Peverel in Essex – Blunts Hall, Billingford, Tolleshunt (Tregoz), and Leigh – passed to him and his descendants. He is found witnessing the charter of the foundation of Snape Priory by William Martel in 1155 [Dugdale, Mon. Angl. iv. 558]; and about that time he was acting as dapifer, or steward, to Henry II's brother William (died 1164) [Cal. Anct. Deeds (P.R.O.), A. 13413]. For some reason his estates were seized into the king's hands in 1171 [Pipe R. 17 Hen. II. 124] and so remained until Geoffrey's death in 1175 [Ibid. 21 Hen II, 77].
