There are conflicting theories as to the origins of the Dukes of Normandy. But the point on which most modern historians agree is that they descend from the Earls of Orkney and that their founding father was Rollo, son of Ragnvald Øysteinsson, the first Earl.
According to the Heimskringla, Rollo was a great Viking, raiding on both sides of the North Sea. However, one summer he chose to “make a cattle foray” on the Norwegian county of Viken, where it was expressly forbidden by the king. This resulted in his banishment from the country of his origins and accounts for his romanticised wanderings as far as the Hebrides and the Ilse of Man and later to what is now Normandy. A more prosaic version seems more likely, that he joined a band of Viking raiders and eventually “subdued for himself a great earldom, which he peopled with Northmen”.
A rival version claims that the Dukes of Normandy were of purely Danish stock and unrelated to the Earls of Orkney. According to the 10th century History of the Normans, a king of Denmark was antagonistic to Rollo’s family, and following the death of his father, his brother was killed and Rollo was expelled from Denmark. Yet another maintains that the family was a combination of Danish and Norwegian, the founding father being Thebotan, Duke of Schleswig and Stormarn. He fled to Norway to escape Danish tyranny in the early 8th century, settling there and taking his two wives from the Norwegian ruling class. That Rollo was a Scandinavian is not in dispute, but as Saxons inhabited most of the territory of this alleged ancestor at the time of his flight, Thebotan might turn out to have been an ethnic German! *DNA testing carried out in 2016 has not resolved the matter, as the bodies contained in the graves of Richard I and Richard II date from the pre-Viking era.
