Louis VI of France
In 1114, Countess Helvise died and was buried at Noyon. William d'Évreux was "struck down by apoplexy" on 16 April 1118, and was buried in Fontenelle Abbey, next to his father. The fact he died without children caused King Henry I of England problems as Count William's nearest relative was Amaury III of Montfort, a vassal of Louis VI of France.
