Hi Graham,
Been trying to pin down records for Colville Armstrong Senior, I note that you give him and younger sibling, Hume, year of birth only, this suggests that you do not have an actual record. Given that records were kept by the Church of Scotland at that time, and are not complete by any means. I have checked Scotsman Archives, andean find no mention of him .
With mother dying in 1837, and father emigrating with brother, Walter in 1840, where did the young Coalville go to stay. Checked the 1841 census for Scotland and England. I have found brother James b 1818, as a tailor, staying in Scotland, traced him through the census to 1881 so far.
Any further info on Coalville Senior's birth would be appreciated.
Tom
