Hello McTosh
I'm sorry for the confusion, you are quite correct - it should be Robert, that's them, I put the wrong name as there are so many Johns in the line I had forgotten he was a Robert!
The story actually comes from two places, as another man who is also distantly related told me (when discussing the family tree) a very similar version which had been passed on verbally in his family - so I think it is very likely to be true. I don't think the brother called Lachlan came to England, as there is a death of someone likely to be him in Edinburgh, but the one called Nicol never crops up anywhere - maybe he died young, or maybe he moved to Northumberland and changed his name. All interesting stuff, just wish I had more time to look into it. Might get a moment later on once I get this mob of current day family sorted out!
