Sorry Elbe don't seem to find one in my tree, that's not saying there's not a connection, just that I've not gone into the McFarlane's in Luss to any great extent.
I do know that there are a lot of Bain's in Luss.
I was going into the Glen's side of my tree, my grandmother's family.
Were you aware that there was a soap called "Take the High Road" which was on British tv during the 80's and early 90's that was filmed at Luss, it was on daily for about 10 years I think. I remember my Dad telling us, but at the time not really taking that much notice, if only.
I will try and do a bit of research and see if I can find them, as if you go far enough back they all seem to be connected, I also have a memorial inscriptions book of Luss grave yard, so will check that out also, sad I know.
Will get back to you.
Regards Tricia.
