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.
Nolasco The first member of the Nolasco family was "Guillaume de Nolasque", a Norman noble who participated in the siege of Nola, in southern Italy, in the eleventh century. Legend has it that, such was his bravery, that he was nicknamed by his fellows "Nolasque" or "Nolasc", which means, in the Italian-Norman medieval dialect, ""the man of Nola"". Guillaume later returned to Normandy and built the Nolasque castle, in Cotentin. He was the husband of Oremburge, a daughter of Serlo I of Hauteville, and had three sons: Geoffroy (1st sire of Vignats), Nicholas (canon in Rouen) and Roger (who stayed in Toulouse, and was the ancestor of saint Peter Nolasco).
