The possible relationship between William de Tracy of Bradninch and
Ralph de Sudeley or lack thereof was discussed by Professor Nicholas
Vincent in The Murderers of Thomas Becket in Bishofsmord im Mittelalter, Fryde, N. & Reitz, D. (eds.). Vandenhoeck & Ruprecht (2003), p. 211-72.
The traditional de Tracy genealogy was also discussed by Jim Weber in
this forum around the time of Professor Vincent's article. https://groups.google.com/g/soc.genealogy.medieval/c/phk02pDyBKk/m/QzN-0rqCHXIJ

A William de Tracy confirmed the gift by his brother, Ralph de Suthleia,
of Janewordem [Yanworth] to St. Peter, Gloucester, which was witnessed
by a Henry de Tracy, Jordan de Cambernun [or Campo Ernulfo], William de
Monte Acuto, Hugh de Ralea [Ralegh], Ralph de Munpinceun [Montpinchon],
Robert de Culna, and Robert de Camrepuls [or Champrepus]. William Henry
Hart, Historia Et Cartularium Monasterii Sancti Petri Gloucestriae, Part
2, p. 180. The witnesses Ralph de Montpinchon and Robert de Champrepus
both assumed their names from places named in the following 1110 grant
to Mont St. Michel from the William de Tracy that Professor Vicent noted
was a close family member to William de Tracy of Bradninch. Circa 1110, William de Tracy, joined the Abbey of Mont St. Michel and granted it the
tithe of his mills at Montpinchon, his wood of Luzerne and the mill of
that vill, the mill of Champrepus, his mills at St. Vigor, the church of Argouges, and the tithe and the tithe of the mill there. The charter was
also signed by his wife, Rohesia, his sons, Turgis and Henry, and his
sister, Gieve. John Horace Round, Calendar of documents preserved in
France, illustrative of the history of Great Britain and Ireland. Vol.1.
A.D. 918-1206 (1899), p. 258. Hugh de Ralegh and Jordan de Campo
Ernulphi who witnessed the charter of William de Tracy brother of Ralph
de Sudeley also witnessed the 1146 charter of Henry de Tracy of
Barnstaple father of Oliver confirming to Barnstaple Priory the gifts by Judhael and Alvred de Totnes. Monasticon, vol. 5, p. 198.

As noted by Professor Vincent, a William de Tracy and a Henry de Tracy witnessed an undated charter with Otuel de Sudeley. However, as noted by Professor Vincent, there is significant uncertainty in the de Tracy
genealogy. As noted in footnotes 119 and 134 of Professor VincentrCOs
article, there is at least one other William de Tracy, son of Gervase de Cuterne or Courteney who was a close family member of William de Tracy
of Bradninch active in Devon during the time at issue with respect to
the Toddington evidences. Further review of the Forde and Torre
Cartularies further complicates the de Tracy genealogy during the period
of the Toddington evidences. For instance, by undated charter dated to 1189-1204, Henry de Traci, son of William de Traci, granted to Forde
Abbey Leoford, Cuntesbury, Linton with the services due by Welhangre, Thornwrthi, Lin, Nerviton and Furzehill within the manor of Barnestapill
to hold by the service of one-half of a knightrCOs fee, and also Colbroc
with the commons of pasture of Braneis, quit of all service. Steven
Hobbs, The Cartulary of Forde Abbey (Somerset Record Society, 1998), p.
114. By undated charter dated to 1226-1246, a Henry de Tracy son of
William de Tracy confirmed to Forde the grant of Colebroc and the grant
of common of pasture in the tenement of Braneis [Bradninch]. Hobbs,
Forde Cartulary, p. 101.
