I havent got a copy of the certificate but do have a copy of the register page and the man at Lambeth Archives who did the search said he looked at it for me and the witnesses were James Rutland and Thomas Steel although the entry i have the surname Steel is ambiguous. It starts with an S but looks like it could be Sh--l??. Groom was George Wardell and Bride was Mary Dongate. The man also said that father's names were not put on the registers in those days so I cant be the only one hitting brick walls on this.

I have him on the 1841 census but he's already married to Mary and living in Lambeth. Only their children are living with them, the same for the 1851 census. As he died in 1860 any Will he may have had will be held in York and not available online so going to send off for a search to see if that helps with any other family members.
