Рено I
Guy was born to Reginald I, Count of Burgundy, and Alice of Normandy. As a younger son, he did not stand to inherit anything. As his mother was the daughter of Richard II, Duke of Normandy, Guy was sent to be raised at the Norman court in the early 1040s. It was hoped that the guardians of his young cousin, William the Bastard, would provide a future for Guy. Guy was William's household companion for a time, and as such did not have the resources needed to challenge ducal authority.
