"That family was supposed to be a branch of the ancient family of Colquhoun, and it is certain that from it spring the Cowans that spread towards the Border"

Colquhoun is the name of a Highland Scottish clan which took its name from a barony lying on the shores of Loch Lomond in Dunbartonshire. The clan’s origins can be traced back to the reign of Alexander II (1214-1249) when Maol Domhnaich, Earl of Lennox, granted the lands of Auchentorily, Colquhoun and Dumbuck to Humphrey de Kilpatrick. It was Humphrey’s son, Ingelram de Colquhoun, who first took Colquhoun as a surname. Colwan, like Cowan, is considered a sept (or division) of the Colquhoun clan.
