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.
Eleanor of Aquitaine Eleanor of Aquitaine (French: "Aliénor d'Aquitaine, Éléonore" , Latin: "Alienora" ; 1122  – 1 April 1204) was Queen consort of France (1137–1152) and England (1154–1189) and Duchess of Aquitaine in her own right. As a member of the Ramnulfids ("House of Poitiers") rulers in southwestern France, she was one of the most powerful and wealthiest women in western Europe during the High Middle Ages. She was patron of literary figures such as Wace, Benoît de Sainte-Maure, and Bernart de Ventadorn. She led armies several times in her life and was a leader of the Second Crusade.
