Well, I've just checked and Ann married James in Brighton which is very near Lewes. Also there is no other suitable marriage for the Ann I have written about above on the Sussex Marriage Index. I would imagine that's the correct Ann and those are definitely her parents. I would say there is a very strong chance that her birth date should read 29 December 1809 rather than 1802 but without checking the original can't be 100% certain.
There's another Ann Pumfrey baptised in 1809 but in Willingdon which is much further from Brighton.
To confuse things further James Harman's wife Ann on the 1851 census gives her birth place as Brighton but I wouldn't necessarily worry about that discrepancy.
