What an article

I wonder what happened to John James Cowdroy who was baptised in 1779? Perhaps he died young, or perhaps he became "Citizen".
On FreeBMD Benjamin's death is shown as Jun 1851 Newington 4 _44 (looking on Findmypast the missing number looks like a 2).
There are two deaths on FreeBMD of Frances Cowdroys.
Mar 1865 St.Geo.East 1c 381 and
Dec 1866 Manchester 8d 273 (age 64).
If she stayed in London after Benjamin died, then the first one would perhaps be "your" Frances. As she came from Portsea, I can't see her going to live in the North of England.
