Stephen of Aumale
In the conspiracy of 1095 against William Rufus, the object of the rebels was to place Stephen on the English throne. Stephen was the first cousin of brothers William Rufus, King of England and Robert Curthose, Duke of Normandy. The leaders were Robert de Mowbray and Guillaume III of Eu, Count of Eu. Stephen was apparently not put on trial himself as he may have been out of the king's reach in Normady. Stephen's father Odo of Champagne lost his English lands for his complicity.
In 1096 Stephen joined the First Crusade, with Robert Curthose, Duke of Normandy. Following the death of King William Rufus, in 1102 Stephen was given back his father's confiscated lands and became lord of Holderness, Yorkshire, England. He sided with Henry I in 1104 against Robert II Curthose but in 1118, when William Clito rebelled against Henry I of England, Stephen supported him, with Baldwin VII of Flanders. He finally submitted to Henry I in 1119.
He married Hawise, daughter of Ralph de Mortimer, Lord of Wigmore and Seigneur de St. Victor-en-Caux, and Mélisende. Their children were :
- Guillaume le Gros (c. 1101–1179), Count of Aumale; married Cecily of Skipton,[a] daughter of William fitz Duncan.
