Rollo might have been a son of Rognvald, earl of More (in present day Norway) and was a Viking raider in France. He probably also raided Scotland and Ireland. Rollo played a part in the Siege of Paris (885–86) and then captured Bayeux according to Dudo of Saint-Quentin. While Rollo was given lands around Rouen in 911 by the French king, Flodoard of Reims says that there were many bands of Northmen raiding in western France at the time. In his writing he paid more attention to another group of Vikings under a Ragenold. Flodoard had no way of knowing then that of all the Viking bands those under Rollo would grow to become the great duchy of Normandy.
