Afraid I can't find a really close match on the marriage. There is one possibility here http://freebmd.rootsweb.com/cgi/search.pl (note: this resource is incomplete) for a James Hardman who married Lambeth Sept Qtr 1844 - amongst the possible brides is a Mary Ann Payne (unfortunately this resource shows a number of grooms and brides rather than which married which), so it's rather risky. I noticed that Mary is born Lambeth on the 1861 census so ... There are other marriages there which may be worth looking through.
