 Thorfinn Torf-Einarsson married into the native aristocracy and his son, Skuli Thorfinnsson, is recorded as having sought the support of the King of Scots in the 10th century in pursuing his claim as Mormaer of Caithness.Njáls saga relates that Sigurd the Stout was the ruler of "Ross and Moray, Sutherland and the Dales" of Caithness and it is possible that in the late 10th century the Scots kings were in alliance with the Earl of Orkney against the Mormaer of Moray.Thorfinn Sigurdsson expanded his father's realm south beyond Sutherland and by the 11th century the Norwegian crown had come to accept that Caithness was held by the Earls of Orkney as a fiefdom from the Kings of Scotland although its Norse character was retained throughout the 13th century.
