- Guillaume (d. 1203)
- Alix d’Alençon, married to Hugh II, Viscount of Chatellerault
- Helie d’Alençon (d. after May 1233), married Robert VI FitzErneis (who was the namesake and descendant of Robert, killed in the Battle of Hastings)
- Phlippa d’Alençon (d. before 1223), married first to William III of Roumare (d. 1198), Earl of Lincoln (grandson of William de Roumare), second to William III Malet, Lord of Graville (possibly the grandson of William Malet, companion of William the Conqueror), and third, to William de Préaux.
Near the end of his life, he planned to participate in the King’s Crusade (the Third Crusade), but died February 24, 1191, at the Chateau d'Alençon. He was succeeded as Count of Alençon by his son John.
