Unfortunately the James Davison from Ballyadrentagh is not the same one as my ancestor James Davison from Crosshill. I have always wondered if there could be a connection further back but haven't been able to find one. The furtherest back I have found is George Davison of Crosshill who died in 1854. I don't know how old he was when he died but he did have a lease on land in 1804 so I would suspect he was in his 70s or 80s. I haven't been able to find out who he married either. If you have research that would be of use I would appreciate you contacting me via pm and I will give you my email address.
