General Notes

[From "The Origins of some Anglo-Norman Families"]

In 1172 William de Tresgot owed the service of one and a half knights in the Cotentin.  He was succeeded by Robert de Tresgoz, probably his son, who was bailiff of the Cotentin in 1195 and under John, and who held lands in many English counties.  Robert adhered to John and lost his lands in Normandy; and in the Registers of Philip Augustus there is the entry "Feodum de Tresgoz quod dominus rex tenet per escaetam debet servicium unius militis et dimidium."  By as charter dated at Paris in Nov, 1218 Philip Augustus gave to Miles de Levis the usufruct of the land which Robert de Tregots had possessed at Tregots, Favarches, and St-Romphaire.  Favarches is the next commune to Troisgots, and St-Romphaire is close by.  There was a castle at Troisgots, described by Gerville.

----------------------

ROBERT DE TREGOZ was probably the son of William DE TREGOZ (who owed the service of 1Ω knights in the Cotentin in 1172), and may also have been the man of that name who was a partisan of the young King Henry (eldest son of Henry II) in 1173 and attested his charters in 1175.  [Complete Peerage XII/2:17-8, (transcribed by Dave Utzinger)]

Note: CP does not indicate any parents for William, father of Robert de Tregoz of Ewyas.  However the line by Dave Utzinger indicates that William was the son of "Le Sire de Tregoz" who fought at the Battle of Hastings.  Clearly Robert, being born around 1169 or not more than a decade before, would not be the grandson of a man born before 1047 (in order to fight in 1066), but he might be the great grandson.  Therefore I am making William a son of William, son of "Le Sire de Tregoz".
