Robert I, the Magnificent
Duke of Normandy
Parents: Richard II and Juduth of Brittany.
Married: Merleve.
Children: William.
Other: It seems he had an older brother who was Richard III, Duke of Normandy; it also seems he was called Robert the Devil, because of the suspicion that he murdered his brother and took the title. (Don't know why I have him listed as Robert II on his son's page...)
