 Old Norse sources mention two Olafs belonging to the ninth-century house of Vestfold.The first of these, Olaf the White, because of his connections with Dublin and with Ketil Flatnose, must be identified with Olaf king of Dublin, as described in early Irish and Scottish chronicles.We are also told in the Heimskringla of Olaf Guthfrithsson of Vestfold who on good archaeological evidence can be identified with the king buried in the Gokstad ship.
