It was wire of Robert II of Bellême, lord d' Alençon, Viscount of Hiémois, lord of Bellême and Count de Shrewsbury, and of Agnès, countess of Ponthieu.
His/her father was a noble Anglo-Norman who, although faithful of William the Conqueror, sought to become independent with dead of this last and frequently revolted against wire of Guillaume. Henri {{Ier}} Beauclerc ends by him to confiscate its English grounds in 1102 and up imprisoning it in 1112. Robert de Bellême had been cruel to his wife, so much so that this one flees, took refuge at the court of Blois, then settled in Ponthieu. She died there between 1106 and 1110 and Guillaume Talvas became count de Ponthieu. In 1119, Henri Beauclerc returns to Guillaume Talvas part of the confiscated fields to his/her father.
To devote itself to its businesses Normans, he entrusts Ponthieu to his son Guy in 1126.

The death of the king announces a war of succession between Mathilde, girl of the king and wife of Geoffroy Plantagenêt, and Etienne of Blois, nephew of the king.
