A polite email request has been sent off.

Cheers, Tony.
Had time to 'inwardly digest' the email I recieved from Chelmsford and nothing could have been nicer! A plot number, a map of the cemetery and a map of the town. 10 out of 10 for Chelsford Cemetery and Crematorium.
Going to find my way there soon, bus pass clutched in my sticky mitt!
Cheers, Tony.
