Commentary
On William’s parents (from Phillips):
In 1157, Henry II confirmed gifts made to the hospital of Falaise by William de Grentmesnil and others [Cal. Docs France, no 1157]. By an undated charter (perhaps from 1160 or later), one Beatrix de Rye gave land to the abbey of St Jean of Falaise, for the well-being of her mother Emma and of her brother William de Grentemesnil [Lechaude d'Anisy, Extrait des Chartes ... dans les archives du Calvados, vol.1, p. 323, no 9 (1834)]. It seems likely that this Beatrix was a daughter of Robert de Grandmesnil by his second wife, Emma d'Estouteville, particularly as the name Beatrix occurs in the Estouteville family, and was possibly borne by Emma's mother [C.T. Clay, ed., Early Yorkshire Charters, vol.9, p.2 (1952)]. If so, this would confirm that Robert also had a son William, who would probably be Pernel's father.
