There is no way you should make such an assumption with such a common name as Christian. You need a viable inter-generation link, such as an aunt or nephew, parents' names off marriage entry or death certificate. Have you found all possibles on the 1841 census. What about illegitimate birthts, they are incorrectly registered on the IGI. Where were the famaily living in the other parishes, was he an Ag Lab? You need to look at each baptism to see if there is any additiional infoormation, Have you got death certificates, obituary notices, so much to check
