Sorry can't help you at the moment, my earliest Samuel is in 1870. I think he was probably born in the Republic of Ireland, I have all the Kernaghan births for Northern Ireland and he does not show. Have you a Mormon Family History Center near you? If you have, then they can get you all the Irish Civil Register on film. If you have no luck, then get back to me and I will see if I can help at a later date.
