Guy de Bourgogne

  Notater:

educated at the court of Normandy, who would lead a revolt for control of the Duchy of Normandy against his cousin William (William the Conqueror). He had to leave his county of Brionne and Vernon in Normandy, after being at the head of the coalition of the barons of Normandy, which was defeated at the battle of Val-ès-Dunes in 1047.[2] Guy found refuge with his uncle Geoffrey II of Anjou. He later attempted to take over the county of Burgundy from his brother William.
