Can one of the managers clean up his father listing?
Included in the list is Robert I "the Magnificent", Duke of Normandy, who is in fact his first cousin. Confusion possibly born from the fact that his father is Robert II (Archbishop of Rouen), not Robert I (Duke of Normandy). Essentially, any reference indicating that Richard d'Evreux is the son of a Duke of Normandy is incorrect, I believe.
