hello
St Mary, Stone and churches in Dartford are on cityark website (!!)
I have looked at St Mary Stone but the burial register stops before this time.
I have looked at Dartford, Holy Trinity but i can't find him using the date given. There are people buried here from Stone asylum and City of london workhouse. ( a new cemetry - an extension was opened in 1856).
Other entries of other churches not available in correct time frame.
sorry Its not of more help
Jane
