The members of this tree are based on the Heimskringla, an account of the lives of the Norwegian kings, which was written in Iceland in the mid 13th century and based on oral traditions, poems and ballads, but also manuscripts. It starts with the mythical god Odin, who is described as a mortal man, and continues with the sagas of individual rulers, blending fiction into fact over its centuries-long span. The accuracy of the early characters can therefore not be guaranteed, but most historians agree that the later sagas are based on real events. It is believed that the genealogies of the main characters have often been adapted to fit into a continuous narrative.
The importance of the family studied here goes beyond the relatively insignificant Earls of Orkney, as they are said to be the progenitors of a great family. The Norwegians claim that they spawned the Dukes of Normandy and, since most modern historians tend to support this version, I have based their genealogy on this premise (see Origins).
