You may note that I edited my last message to include possible siblings (nobody else had posted after me when I went to edit it and I dislike posting twice in a row).
There's a possible death for Charles Snr bd. 27 Oct 1837, Stoke Damerel, abode Pond Lane, no occupation details, aged 64. This would mean he has a death cert- GRO 9 233.
Conveniently there is a christening for 26 March 1773, Stoke Damerel, son of Charles and Grace.
I didn't see a death for Ann, however. The death cert of Charles, with any luck, might help confirm matters (provided it is indeed the same man) if your ancestor was the informant. Or, even better, if his dau in law was informant!
Good luck with it

-Edit
Ann is still alive on the 1851 census, living with dau Elizabeth, now the wife of James PROWSE. It looks like Ann dies in 1857, Stoke Damerel, d. 17th Jul, bd. 22nd Jul 1857, aged 83, abode 52 Cornwall St. This is the address of dau Elizabeth on the 1861 census.
