Hi Karen, it's Senga here again. i just did a search on the Scotland's People site for John Ballantynes birth. I worked out going by the age on the census if correct he would have been born around 1816 so I did a search of 1815-1817 which returned 7 matches. Also you mentioned that he was listed as being born outside the census county, did it list where he was born as that might help us narrow things down. Sorry but I have run out of credits for Scotland's People (again ...LOL ...expensive habit this) so I will paste in below the entries I found. When I get more credits I will look into it further if I can, if you get around to it before me then please let me know
