Hello from Bermuda. The info you are looking for can be either found at the Bermuda Library on Micro film - info taken from the obits of the newspapers showing deaths/burial info. You would have to ask them to do the research for you?????
Or the death notice can be purchased from the Registrar General's office in Hamilton, Bermuda.This document will not show the grave site.
Sorry I cannot do the research for you. cheers, Judy
