Many thanks indeed for your email. Sorry I haven't replied earlier but due to changing family lines with my research I have forgotten about this site.
I am guessing, but haven't checked with the Essex Records Office in Chelmsford, that the person I am / was looking for may be buried at the church in Bowers Gifford at the end of North Benfleet Hall Lane. I believe it was a CofE church but is now closed. By looking at Google Maps the church still stands but in the grounds of a large farm like area... I may visit and view one day. Her parents lived in Bowers Gifford at the time.

Kind Regards
Tim
