If I have a chance, I will visit the church and look for the most recent grave Frank.
You could try writing to David ?Lambert? c/o Rectory, St. Chads, Clayhill Road, Vange, Essex to ask if the past church warden (david) or anyone else can help you in your search. Not positve his name is lambert. He mapped every single Grave, marked and unmarked, and can point you in the direction of those that are buried in years of undergrowth or behind trees and scrubs that have grown up since the 1950s. Will be a little while before I get there as I have been having hopital treatment (what fun!)Denise
