I'm only going by the earlier post by Blemdookie. I didn't realise that there were so many places called Ballymoney in Ireland or even within Co Antrim. I don't know where James Wilson married his first wife, but their daughter Martha Matilda Wilson was born in Sligo in 1849, although again, I don't know exactly where in Co Sligo. Perhaps his first wife was from Co Sligo? Or maybe there was an army barracks there? The search continues ,,,
