The Story of Grettir the Strong

There was a man named Onund, who was the son of Ufeigh Clubfoot, the son of Ivar the Smiter; Onund was brother of Gudbiorg, the mother of Gudbrand Ball, the father of Asta, the mother of King Olaf the Saint. Onund was an Uplander by the kin of his mother; but the kin of his father dwelt chiefly about Rogaland and Hordaland. He was a great viking, and went harrying west over the Sea. Balk of Sotanes, the son of Blaeng, was with him herein, and Orm the Wealthy withal, and Hallvard was the name of the third of them.
