The traditional progenitor of the MacLeods was Leod, made a son of Olaf the Black, King of Mann and the Isles, by a now-discredited tradition. An older, more accepted tradition names his father Olvir and describes the clan as Sliochd Olbhur. Tradition gave Leod two sons, Tormod - progenitor of the Macleods of Harris and Dunvegan (Sìol Thormoid); and Torquil - progenitor of the Macleods of Lewis (Sìol Thorcaill). In the 16th and early 17th centuries the chiefly line of the Clan Macleod of The Lewes was nearly extinguished by the bloodthirsty and power hungry chief "Old Rory" and his various offspring. This feuding directly led to the fall of the clan, and loss of its lands to the Clan Mackenzie. One line of the 16th century chiefly family, the Macleods of Raasay, survived and prospered on their lands for centuries thereafter. The current chief of Lewis descends from this latter family.
