 In the year of Haraldr Óláfsson's drowning, two prominent members of Clann Somairle, Eógan mac Donnchada, Lord of Argyll (died in or after 1268) and his second cousin Dubgall mac Ruaidrí (died 1268), travelled to Hákon in Norway and requested the title of king in the Hebrides. Hákon subsequently bestowed the title upon Eógan, and in 1249, upon learning of Haraldr Óláfsson's death, Hákon sent Eógan westward to take control of the Hebrides. In May 1249, Haraldr Óláfsson's brother, Rögnvaldr Óláfsson (died 1249), formally succeeded to the kingship.
