Later King Harald married his sister Swanhilda and had issue, In (?) 874 King Harald made an expedition to the Nordreys (Orkney and Shetland) to enforce his authority over those who had fled thither in order to escape from it in Norway. Either during this expedition or previously at the battle of Hafrsfiord circa 872 Ivar, the eldest son of Ragnvald, was killed and the King gave the Orkneys and Shetlands to Ragnvald as compensation. When the King started home for Norway, (?) Spring 875, Ragnvald, who went with him, gave the islands to his brother Sigurd, and the King confirmed the transfer, Ragnvald was surprised in his hall and burned alive circa 894 by Halfdan Haaleg and Gudred Liomi, King Harald's sons by Snaefrid, dau. of Swasi.
