Leod, son of Olaf, King of Man, is the progenitor of this clan. They acquired Dunvegan at an early date. The MacLeods of Dunvegan and Harris are known as Siol Tormod, and the MacLeods of Lewis as Siol Torquil. The MacLeods of Dunvegan and Harris are recognised as the senior family. They were a powerful clan and had great influence in the Highlands. The 13th chief, Rory Mor, was knighted in 1603 by James VI. They supported King Charles II at Worcester in 1651, when almost 700 MacLeods are said to have been killed. They did not support the Jacobite Risings of 1715 and 1745.
