Emma de Lacy, Nun at St. Amand

Orderic Vitalis wrote (in The Ecclesiastical History of England and Normandy, Volume 3, p. 277) "Ilbert de Lacy and his mother Havise were owners of Bois l"Eveque, near Darnetal." He also posits Engerrard, son of Hilbert, as being Ilbert's son. "For genealogy of this family, see Monastic. Anglican, p. 859)."

Richard Holmes, in Pontefract: Its Name, Its Lords, and Its Castle (1878): [Notes, not quoted, from p 65ff]

• Enguerrard de Lacy was governor of Caen in 1106
• Hugh de Lacy, youngest son of Ilbert, became Abbot at Selby in 1069--so Ilbert, as Lord of Pontrefact, contributed the Manor of Hambleton towards the Abbey's maintenance.
• Otherwise, little to nothing is known of Ilbert other than that he founded or rebuilt Pontrefact Castle and its Church of St. Clement
• he survived King William since he received from King William Rufus granting him chastelery of his castle and in those of the Bishop of Bayeux
• author is skeptical about Dugdale who said Ilbert was buried at the right corner of the altar of St. Benedict (probably in St. John's monastery in Pontrefact) and who proposes a family tree of Ilbert I then Robert then Ilbert II
• his wife was Avisia or Hawise (mother of Robert)
• It is probable but unproved that Ilbert and Hawise were owners of Bos-l'Eveque, near Darnetal near Rouen. and that Emma de Lacy (a nun at St. Amand) was Ilbert's sister
• Enguerrand, son of Hilbert (i.e. Ilbert) was a benefactor to the nunnery in which Emma lived
