Thank you CaroleW for your reply.
I have found the above entry but to complicate matters, there is another family James (born 1789, a gardener) and his wife Sarah. Either could be his family. I have a situation where the census doesn't appear to help and whilst I cannot find his baptism, I can only guess, which I don't like doing.
As far as the occupation is concerned, between 1841 and 1856 (when Jesse got married) his occupation could have changed, or his occupation could have been altered on purpose, who knows!
Thanks for helping.
Has anyone else got any ideas how I can proceed please?
Andy
