Bjørn Farmann

In late tradition, Bjørn Farmann was made the great-grandfather of Olaf II of Norway, through a son Gudrød Bjørnsson.

Erik Bloodaxe (Old Norse: Eiríkr blóðøx, Norwegian: Eirik Blodøks) was the eldest son of Harald Fairhair and became the second king of Norway (930–934).

King Bjorn had also merchant ships on voyages to other lands, by which he procured for himself costly articles, and such things as he thought needful; and therefore his brothers called him Farman (the Seaman), and Kaupman (the Chapman).

Eirik Blood-axe came from his Baltic cruise with ships of war, and a great force, and required his brother Bjorn to deliver to him King Harald's share of the scat and incomes of Vestfold.

But this work was taken very ill by the people of Viken, and Eirik was much disliked for it; and the report went that King Olaf would avenge his brother Bjorn, whenever opportunity offered.
