Thanks for your responses everyone.
His wife died more than 40 years later (he was only early 40's when he died), had remarried and I was lucky enough to visit her grave in Heathcote while there.
I have just sat here with a magnifying glass trying to read the letters on the plan, can make out Area C and F, but that is all. However, on the site it says there is a plan which was drawn up in 1875 in the sextons office.
I did not have the inquest index, so thanks for that.
Will have to wait and here from the Cemetery Trust.
