Thanks for your message Rick Sinclair.
Kilmartin is at the top end of Loch Awe, whilst Dalmally is at the other end. Lochgilphead is nearby Kilmartin. Do you have any further information on how or where these Sinclairs got to Argyll.
As far as i'm aware none of my Sinclairs went to North America.
Cheers, Donald Sinclair
