Alys was the daughter of King Louis VII of France and Constance of Castile his second wife. A marriage agreement was arranged between Alys and the son of Henry II, Richard who would become King Richard I, the Lionheart. Alys was only a child and until she was old enough to be married lived under the protection of the English King. The marriage never took place and Richard married Berengaria instead. Alys' half-brother Philip II of France fined Richard for not marrying her. It was rumoured that King Henry had made Alys his mistress and this was the reason that Richard did not marry her. After Henry's death Alys returned to France and in 1195 was married to William III Talvas, Count of Ponthieu who was almost twenty years younger than her. With William she had several daughters.
