  Research Notes:

The Tale of Ragnar's Sons (Ragnarssona þáttr) tells that he was the son of the Scandinavian king Ragnar Lodbrok and Aslaug, whom some call Randalin, and that he had the brothers Hvitserk, Ivar the Boneless and Sigurd Snake-in-the-Eye, and the half-brothers Fridleif, Eric and Agnar.

Björn and his brothers left Sweden to conquer Zealand, Reidgotaland (here Jutland), Gotland, Öland and all the minor islands. They then settled at Lejre with Ivar the Boneless as their leader.
