[HASCULF d´Harcourt .  The Genealogia Fundatoris of Tintern Abbey, Monmouthshire names ”Turketillus…frater…Turulphi, cuius filius Hasculfus d´Harcourt” married “aliam sororem…comitissæ Gunnoræ” by whom he was father of “duos…filios…Walterum de Giffard primogenitum…”[3496].  This is contradicted by Guillaume of Jumièges who Guillaume de Jumièges records that "Gunnor" had “excepta Sainfria...duas sorores Wewam et Avelinam”, adding that “tertia...sororum Gunnoris comitissæ” [Aveline, from the context] married “Osberno de Bolebec”, by whom she had “Galterium Giffardum primum et Godefridum patrem Willelmi de Archis”[3497].]
