I made a note of the inscriptions (about 100 that I could read) in St Paul's churchyard a few months ago. The only Moxon I have is:
In Affectionate Remembrance of
Margaret Moxon
who died December 22nd 1871
aged 55yrs
It is the Lord Let him do what seemeth good
There is another cemetery nearby - usually referred to as Morton Cemetery, and I'll try to have a look around there soon.
