Clan Macleod of The Lewes, commonly known as Clan MacLeod of Lewis, is a Highland Scottish clan, which at its height held extensive lands in the Western Isles and west coast of Scotland. From the 14th century up until the beginning of the 17th century there were two branches of Macleods: the MacLeods of Dunvegan and Harris (Clan MacLeod); and the Macleods of Lewis. In Gaelic the Macleods of Lewis were known as Sìol Thorcaill ("Seed of Torquil"), and the MacLeods of Dunvegan and Harris were known as Sìol Thormoid ("Seed of Tormod").
