tradition suggests that he may have been a brother. According to William of Jumièges he died in Frisia, which also had an association with the invaders of England. Ubbe is sometimes labeled the "Frisian Jarl" and the invaders are occasionally called Scaldingi (men from Schelde). The kingships of Björn is at times historically problematic since it is not supported by older sources and presents insurmountable chronological inconsistencies. In fiction A principal character in the History television series Vikings, played as a young boy by Nathan O'Toole and through adulthood by Alexander Ludwig, is loosely based on the historical character and portrayed as the son of Lagertha, rather than of Aslaug. According to the lore, Björn is not the eldest son, while in the show he is the eldest of all the sons of Ragnar. In the novel Monster by Michael Grant, one character, Armo, mentions that he's descended from "Björn Ironside, a very badass Viking".
