I've said it a million times before: The Scots, the Irish, and all other Celtic types are basically the same, but now I have new evidence specific to my own family:
The Colquhouns originated in Ireland. In the early thirteenth century the founder of the clan, Humphrey Kilpatrick, was granted a charter for the barony of Colquhoun on the western bank of Loch Lomond.
Slainte to all my Kilpatrick cousins! ;)
