Question: The Abbey of Saint-Étienne was founded by a descendant of who?

<P0-S0>  A descendant of Rollo, he was Duke of Normandy (as Duke William II) from 1035 onward. <P0-S1> 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. <P0-S2>  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. <P0-S3>  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. <SEP> <P1-S0> The Abbot and then Commendator of Melrose was the head of the monastic community of Melrose Abbey, in Melrose in the Borders region of Scotland. <P1-S1>  The abbots of the earlier Northumbrian foundation from Lindisfarne are not included here. <P1-S2>  The second abbey was founded in 1136 on the patronage of David I ("Dabíd mac Maíl Choluim"), King of Scots, by Cistercian monks from Rievaulx Abbey, Yorkshire. <P1-S3>  Control of the abbey was secularized in the 16th century and after the accession of James Stewart, the abbey was held by commendators. <P1-S4>  The last commendator, James Douglas of Lochleven, resigned the abbacy to William Douglas, 6th Earl of Morton (his nephew) in December 1606, and the abbey itself to the king in 1608. <P1-S5>  The abbey (or most of its lands) was then erected into a secular lordship for viscount Haddington, John Ramsay, who in 1609 was created "Lord Melrose". <P1-S6>  Lochleven however resumed the title of commendator in 1613 until his death in 1620. <SEP> <P2-S0> Vauluisant Abbey, near Courgenay in the canton of Brienon-sur-Armançon, Yonne, France, is a Cistercian abbey founded in 1127 by a group of monks from the abbey of Preuilly (Seine-et-Marne) who came to settle between the forest of Othe and the forest of Lancy, an area near the borders of Ile-de-France, Champagne and Burgundy that had come to be far from human habitation. <P2-S1>  They diverted the waters of the little River Alain and by 1 April 1129, works were far enough advanced for Henri Sanglier, the archbishop of Sens, to consecrate the modest oratory. <P2-S2>  By 1140 Vauluisant was fully operational. <P2-S3>  The abbey church was consecrated in 1149. <P2-S4>  In the second half of the 12th century, granges were established to cultivate abbey lands far from the abbey itself, at Beauvais, Toucheboeuf, Livanne, Cérilly, Armentières, worked by lay brothers who lived communally. <P2-S5>  Ironworks were established, fuelled by the dense woodlands, and tileworks, whose kilns were also fired by forest timber. <P2-S6>  The energetic Cistercians of Vauluisant produced more than the abbey needed; the surplus was sold in the market towns of Troyes and Provins, where the abbots retained domiciles, and at the cathedral town of Sens. <SEP> <P3-S0>  It was founded in 1063 by William the Conqueror and is one of the most important Romanesque buildings in Normandy. <P3-S1> The Abbey of Saint-Étienne, also known as Abbaye aux Hommes ("Men's Abbey") by contrast with the Abbaye aux Dames ("Ladies' Abbey"), is a former Benedictine monastery in the French city of Caen, Normandy, dedicated to Saint Stephen.
