Introduction
Raoul II de Tosnyseigneur de Conches-en-Ouche (died 9 April 1102) was a Norman nobleman of the House of Tosny, son of Roger I of Tosny. He was active in Normandy, England and Wales.
Victor at Hastings in 1066
He is one of the few proven companions of William the Conqueror known to have fought at the Battle of Hastings in 1066. Tradition says he gave up the role of standard bearer, his hereditary office, to Walter Giffard, in order to be able to fight closer to William, duke of Normandy.
Marriage
He married Isabel de Montfort, daughter of Simon I de Montfort. There was a feud with Guillaume d'Evreux and his wife Helvise de Nevers, recorded by Ordericus Vitalis. This came to open war in 1091–92, when Guillaume attacked Conches. A settlement was reached. They later co-operated in attacking Robert de Beaumont, 1st Earl of Leicester's county of Meulan.
In England
He had widely spread holdings, as recorded in the Domesday Survey. His seat was at Flamstead in Hertfordshire. He held Clifford Castle. It is also believed that he held assets in the village of Hose, Leicestershire, which was split into two manors, Tosny's and that of the title holder of the Norman Belvoir Castle.
Family
Robert de Stafford was his brother.
His second son, Raoul IV de Conches, was his surviving heir. He married Alice of Huntingdon, daughter of Waltheof, Earl of Northumbria, and Judith of Lens.
His daughter Godehilde married Baldwin I of Jerusalem.
