Simon, Thanks for your reply(s). McCulloch certainly seems a pretty common name in Wigtownshire. I can't see an obvious link to your Thomas, yet. I have a direct relationship with Alexander McClaren's McCulloch lineage. The hurdle I have is getting back further on Thomas' father John, born in Ireland. A brickwall of a place for most family researchers. I'm focussing my time on expanding the facts I've currently got on the family & learning as much as is possible about their lives. cheers Rob
