Hello Again
Ive had the chance to look at all the census you refer to and see what you say about James being wrong - I nver picked up on that. This does indeed sound like the most likliest match as its the only Jospeph coming up thats born in 1852.
Ive checked the IGI and it seems strange that all of Thomas Quilliam and Ann Kneales children were baptised and in the same batch number - except Joseph. There is a joseph who was baptised in April 1852 but the mothers name does not seem to match up.
Any ideas?
