you said: > That's awesome information, and ties in with what I already have (that Susan's mother's maiden name was Campbell) Thanks for that. I've looked quite a bit for William Jackson - from his will I know that he was born around 1806 (poss. a year either side) which narrows it down a bit, but as this was roughly the time of the highland clearances I don't want to rule out him being from outside Glasgow. Furthermore, if I trace back through what I consider to be the most likely, how can I categorically prove that this is the correct line? > > Thanks again for the info ** IT is not always possible to prove some links, but try avenues such as the National Archives of Scotland (NAS) online catalogue; look for gravestone inscriptions (M.I.s); census records such as 1841; and the Glasgow Room at Glasgow's Mitchell Library.
