Hi,
I see this post is a few years old now, so wasn't even sure whether to reply but you never know...
The previous quoted post from 2011, was done by myself when a few years ago I looked into it but got no response. Recently I have started to see what was out there again as I now know more and that my grandad's brother was Henry George Jordan Fairbairn (born 1903) in Glasgow and married a Dorothy King- unable to find a marriage listing for them on scotlandspeople I googled their names and found this thread, obviously discovering they married in Northern Ireland. So while I am not directly linked to Dorothy's side, I am to Henry's. My grandad was George Fairbairn and his mother Mary Ann Macdonald. I have looked further back before on that side before, but would need to look again to remember any names!

Anyway, if OP does happen to see this then great.

I don't know then if your friend's family moved back to Scotland or remained in Northern Ireland, as I am pretty sure Henry was in Scotland when he died.
