William II Talvas

William I Talvas ( – c. 1060 He obtained the lands of Bellême from his brother Yves de Bellême, Bishop of Séez who held them of the King of France while Alençon was held of the Duke of Normandy and Domfront of the Count of Maine

While as treacherous and self-serving as any of his family before him he surpassed them in wickedness and cruelty. He had married Hildeburg, daughter of a nobleman named Arnulf, who bore him two children. According to Orderic, William had her strangled on her way to church, because she loved God and would not support his wickedness.

Among the private feuds going on during the minority of Duke William was one that erupted between William Talvas and William fitz Giroie. William fitz Giroie was a vassal of William Talvas and his father Giroie, Lord of Échauffour had assisted Talvas' father and uncle in the struggles against Herbert I Wake-dog, Count of Maine. William fitz Giroie himself had greatly assisted William Talvas in obtaining his own lands, apparently by force. William fitz Giroie immediately razed his own castle to free his lord and in return Geoffrey de Mayenne built fitz Giroie a new castle at St. Cenery on the river Sarthe. This apparently caused great resentment in William Talvas. To avenge this atrocity the sons and kinsmen of William fitz Giroie sacked and destroyed the lands of William Talvas who would not face them in the field. Finally, Talvas' son Arnulf rebelled and exiled his father, now reviled by everyone.

His second wife, a daughter of Ralf de Beaumont, may have been the mother of his son:

Oliver who after long service in the wars, became a monk at Bec.
