The Abbey of Saint-Étienne was founded by a descendant of who?
William the Conqueror William I (c. 1028 – 9 September 1087), usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy (as Duke William II) from 1035 onward. After a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands and by difficulties with his eldest son.
Wulgrin I of Angoulême Wulgrin (or Vulgrin, Woulgrin) I (c 830 – 3 May 886) was the Count of Angoulême, Périgueux, and possible Saintonge from 866 to his death. His parents were Vulfard (Wulfard), Count of Flavigny, and Suzanne, who was a daughter of the Bego I, Count of Paris. His brother Hilduin the Young was the abbot of Saint-Denis. Another brother was Adalard of Paris. Ademar of Chabannes is the chief source on his active reign in preserving and moulding Angoulême.
