Hawise possible wife of Osbern de Bolbec

Charles Cawley posits that Osbern de Bolbec:

[m secondly HAWISE, daughter of --- (-bur [Saint-Etienne de Fontaines]). 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[647]. It is supposed that "Osbernus Giffardus" refers to Osbern de Bolbec, given that his son used the name Giffard. If this is correct, Hawise was presumably his second wife, unless "Aveline" is an error for "Hawise" in Guillaume de Jumièges and Robert de Torigny which names Osbern´s supposed first wife.
