"Ricardus de Roll[os]" is named holding land "in Thorp et in Twyford" in Lodinton Hundred, Gosecote Wapentake in the Leicestershire survey, dated to [1124/29]. The 1130 Pipe Roll records "Baldwinus filius Gisleb" for "terra Willi de Rullos cum filia Ric fratris sui" in Lincolnshire. The 1130 Pipe Roll records "---ic de Rullos" in Westmoreland. “Richard de Rollos" donated the church of St Martin of Rollos to the priory of Saint-Etienne, Plessis-Grimould, with the consent of "his sons Richard and Robert”, by charter dated to [1130].
Domesday Descendants cites a charter which names Richard de Rollo’s wife as Emma and suggests that she was one of the daughters of "the Breton Enison Musard" who held a fief in the honour of Richmond, later recorded as held by Richard. Ingulph's Chronicle of the Abbey of Croyland records that "Richard de Rulos" married "the daughter and heiress of Hugh de Evermue, lord of Brunne and Depyng". If this is correct, she was [Emma] de Evermou, daughter of Hugh de Evermou & his wife --- de Bourne. Round dismisses this alleged parentage and marriage as chronologically impossible, although his explanation of the chronological difficulties does not appear to be correct. Nevertheless, Ingulph’s Chronicle is, in any case, of dubious authority. 1
