Роберт Сильный
With his brothers, Berengar and Waldo, Abbot of St Maximin's, Trier, he took part in the 861 revolt of Carloman of Bavaria, possibly his cousin-in-law, against Louis the German. The revolt was crushed, and the three brothers fled with their relative Adalard to the court of the West Frankish king, Charles the Bald, who granted them wardship of the march held against the Vikings while the march against the Bretons was granted to Robert the Strong.
