a member of the Meic Somairle. One possibility is that he was a son or grandson of Óspakr. Another is that he was a descendant of Ruaidrí. If Óspakr was indeed a forebear of Ruðri, the latter's actions on Bute may relate to the campaign of 1230, and may have been undertaken in the context of settling old scores. The castle itself—and the surrounding settlement of Rothesay—may owe its name to Ruðri, or perhaps to an ancestor of his. As for Óspakr's brothers Dubgall and Donnchad, nothing further is known of the former, whilst the latter went on to represent the Meic Dubgaill into the mid part of the thirteenth century. The latter was a significant mainland magnate within the Scottish realm, and the fact that he is not recorded to have contributed to Óspakr's campaign after his release could be indicative of an attempt to accommodate the Meic Dubgaill's conflicting allegiances to both the Norwegian and Scottish Crowns.
