Chi uscì con Robert I, Duke of Normandy?

Robert I of Normandy (22 June 1000 – 2 July 1035), also known as Robert the Magnificent and by other names, was a Norman noble of the House of Normandy who ruled as duke of Normandy from 1027 until his death in 1035. He was the son of Duke Richard II; the brother of Duke Richard III, against whom he unsuccessfully revolted; and the father of Duke William who became the first Norman king of England after winning the Battle of Hastings in 1066. During his reign, Robert quarrelled with the church—including his uncle Robert, archbishop of Rouen—and meddled in the disorder in Flanders. He was finally reconciled with his uncle and the church, restoring some property and undertaking a pilgrimage to Jerusalem, during which he died.

Arlette de Falaise (ou Herleva, Erlève, Herlève, Herlotte, Herlotte), née vers 1010 et morte vers 1050, est la concubine du duc de Normandie Robert le Magnifique. Elle est la mère de Guillaume de Normandie puis, après son mariage avec Herluin de Conteville, de deux autres fils : Odon de Bayeux et Robert de Mortain.
