Роберт Сильный
His ancestry is not known for certain. Onomastics would place him in the extended family of Odo I, Count of Orléans. The most recent studies make him a son of Robert, Count of Oberrheingau and Wormsgau, and Waldrada, a daughter of Odo of Orléans. If this theory is true, he was the elder brother of Robert the Strong.
