Searching for deaths/burials of William and Hannah Freeman

[ElizabethHerts]

William and Hannah Freeman married in 1810.

They had 3 children: William (1812). Mary (1816) and Samuel (1817, who must have died young). They were born in Gloucestershire.

I have now noticed William and Mary both married at St Mary, Lambeth in 1839 and 1836 respectively. I'm wondering whether the whole family lived here as I can't find their parents' burials in Gloucestershire/Warwickshire.

I'll have another look again but so far I have drawn a blank. The affidavits in the Chancery case don't have details of their deaths.
