I'm researching the above and wondered whether anyone would be able to look up his burial for me.
There is a transcript on FindMyPast and Ancestry for Frederick which says he was buried at St Lawrence, Winchester, on 14 Aug 1796. Hampshire have added their BMD original records to Ancestry, however the copy of that original page is unreadable.
Given that a transcript exists, someone must have ben able to read the original at some time. I'm just trying to find out whether the burial provides any additional information.
Many thanks
