Wearing my kilt (Black Watch) to church on Sunday a man of Jamaican family asked me what I could find out about his family name, Duncan.

I went back and consulted my copy of the Collins Scottish Clan Encyclopaedia and could find no mention.

A Google search came up with a website for Clan Duncan, which appears to be of great antiquity but merged with the Robertsons a few centuries back.

I thought someone here will no a bit more about it, so rather than googling away I thought it more fun to start a thread here.

(There's the interesting question of West Indians with Scottish names, but I'll start another thread some time.)
