  Research Notes:

"Duke Richard [II]" donated property to the abbey of Mont Saint-Michel by charter dated to [1026], subscribed by "…Osbernus frater comitisse, Hunfredus frater eius…" It is assumed that "comitisse" in this document refers to Gunnor, wife of Richard [II] Duke of Normandy, and that "frater comitisse" should be interpreted as "brother-in-law". A manuscript at Caen, which commemorates the death of Abbess Mathilde, daughter of William I King of England, names "Osbernus Giffardus, Haduisa eius conjunx" among the deceased at "sancti Stephani Fontanensis", presumably indicating that they were buried there. It is assumed that "Osbernus Giffardus" refers to Osbern de Bolbec given that his son used the name Giffard. "...Osbernus avunculus comitis, Walterius fr. eius..." subscribed the charter under which Guillaume Duke of Normandy donated the church of Arques to Saint-Wandrille, dated to [1035/55]. ¹
