Richard and Joannah Mansell deaths

[Mansl]

Hi everyone.

I have Richard Mansell marrying Joannah Jackson at Dowdeswell on 30/5/1748.

I don't know when either of them were born or baptised or who their parents were.

I would like to find when they died, I have found two of their children Thomas Bapt. 25/12/1748 Dowdeswell and Alice Bapt. 3/2/1754 Whittington.

I haven't found any other children as yet.

I would like to find when Richard and Joanna(h) died.

Alan
