Thanks so much. Apologies for not reading this post sooner, I somehow didn't get email notification.
Yes, this is certainly the guy I am looking for. Since posting I found four children, Jane b. 1850, Jane b. 24 March 1858 (my ancestor), John William b. 1853 and Margaret Helen b.1855.
I had worked out he had married a Rachel, but only knew that it was probably Hunter.
If you have any further information, I would be very happy to read it.
Thanks once again.
