Notes - "The death by drowning of William Atheling, King Henry's only legitimate son, on 25 November 1120 transformed William Clito's fortunes. He was now the obvious male heir to England and Normandy, and a significant party of Norman aristocrats adopted his cause. Henry's problems became worse, as his son William Atheling had been betrothed to Matilda of Anjou, daughter of Count Fulk V of Anjou and Fulk wanted her dowry, several castles and towns in Maine, returned, which Henry refused. Fulk in turn betrothed his daughter Sibylla to William Clito giving him the county of Maine, between Normandy and Anjou, as her dowry. King Henry astutely appealed to canon law, however, and the marriage was eventually annulled in August 1124 on the grounds that the couple were within the prohibited degrees of consanguinity."
