(Origin Scottish) This family was for many centuries reputed the most powerful of any in the Highlands of Scotland, being styled 'King of the Isles,' for many generations, during which they were successful in asserting their independence. Somerled, Thane of Argyle, flourished about the year 1140, and was the ancestor of all the McDonalds. He married the daughter of Olans, Lord of the Western Isles, whereupon he assumed the title of 'King of the Isles.' He was slain, in 1164, by Walter, Lord High Steward of Scotland. Donald, from whom the clan derived their name, was his grandson.
