Hi Adrian and Beenie
Given that John's birth was illegitimate, I wonder if this is him in 1851 with his maternal grandparents under the name of McCulloch - everyone showing as born in Mochrum:
James McCulloch 51, thatcher
Anges McCulloch 51
Jane McCulloch 21, general serv.
Janet McCulloch 14, daughter
Agnes McCulloch 6, daughter
John McCulloch 4, grandson
Address: Boghouse, Mochrum
If we have the right family, hard to say who his mother could be at this stage...Jane showing above or another daughter to James and Agnes?
Do you know where John married, have you tried to find his marriage or death certs.?
Regards.
Monica
