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”.
Vicomte d'Arques, which he presumably inherited from his father-in-law “Willelmus...comes filius...Ricardi Normannorum quondam ducis” restored “insulam in fluvio magno Secane...Belcinaca...ecclesias eciam Vatheuille et Brotonii” to Saint-Wandrille by charter dated to [1032/47], subscribed by “Godofredi vicecomitis, comitis, Walterus filius, Lambertus, Willelmus, Osbernus”. 1
