The Scottish surname Calhoon is an habitational name from the barony of Colquhoun in Dumbartonshire. The name appears to derive from Gaelic còil, cùil ‘nook’, ‘corner’, or coill(e) ‘wood’ + cumhann ‘narrow’. In the 13th century Maol Domhnaich, Earl of Lennox granted the lands of Colquhoun to Humphry de Kilpatrick. Humphry’s son, Ingelram de Colquhoun, who lived in the reign of Alexander III, was the first person recorded as taking Colquhoun as a surname.[2] Around 1368, Luss, on Loch Lomond, was acquired by Sir Robert Colquhoun through marriage. From then on the chiefship  has been described as of Colquhoun and Luss. Today there are 2,200 people with the last name living in The United States.
