[530] William de Sai had married Beatrice, sister (and, in her issue, heiress) of the earl, by whom he was ancestor of the second line of Mandeville, Earl of Essex. In the following year he joined the earl in his furious revolt against the king. [531] This was William "Capra" (_Chévre_), whose family gave its name to the manor of "Chevers" in Mountnessing, county Essex. He was probably another brother-in-law of the earl, for I have seen a charter of Alice (_Adelid[is]_) Capra, in which she speaks of Geoffrey's son, Earl William, as her nephew ("nepos"). There is also a charter of a Geoffrey Capra and Mazelina (_sic_) his wife, which suggests that the name of Geoffrey may have come to the family from the earl. Thoby Priory, Essex, was founded (1141-1151) by Michael Capra, Roesia his wife, and William, their son. The founder speaks of Roger fitz Richard ("ex cujus munificentiâ mihi idem fundus pervenit"), who was the second husband (as I have elsewhere explained) of "Alice of Essex," _née_ de Vere, the sister of Earl Geoffrey's wife. A Michael Capra and a William Capra, holding respectively four and four and a half knights' fees, were feudal tenants of Walter fitz Robert (the lord of Dunmow) in 1166. [532] William, son of Walter (Fitz Other) de Windsor, castellan of Windsor. In the Pipe-Roll of 31 Hen. I., he appears as in charge of Windsor Forest, for which he renders his account. It is probably to this charter rather than to any separate grant that Dugdale refers in his account of the family. [533] This is an unusual name. As William de Say is mentioned just before, it may be noted that his son (Earl Geoffrey's nephew) promised (in 1150-1160) to grant to Ramsey Abbey "marcatam redditus ex quo adipisci poterit quadraginta marcatas de hereditate sua, scilicet de terra Roberti _de Rumele_" (_Chron. Ram._, p. 305). Mathew de Romeli, according to Dugdale, was the son of Robert de Romeli, lord of Skipton, by Cecily his wife. A Mathew de Romeli, with Alan his son, occur in a plea of 1236-7 (_Bracton's Note-Book_, ed. Maitland, iii. 189). [534] Geoffrey de Tourville appears in 1130 as holding land in four counties (_Rot. Pip._, 31 Hen. I.). [535] William de Ou (Auco) or Eu is returned in the _carta_ of the Earl of Essex (1166) as holding four fees of him. [536] See Appendix Q, on "Osbertus Octodenarii." [537] Dodsworth's transcript begins again here, and is continued down to "Belloc[ampo]." [538] "Comes Herefordiæ" (Dug.). [539] So also Dodsworth; but Dugdale wrongly extends: "Robertus filius Reginaldi." See p. 94, _n._ 4.
