The easiest way is to find a headstone and then search for that person in the burial records on the left. You will then know where you are. If you are nowhere near find another until you get closer. Keep searching the burial records and you will find the plot you want. If you can't I can look for you if you let me know.
thank you to everyone . i combined all the tips and today managed to find 2 of the 4 graves i was searching for and the possible location of the other 2 although there was no headstone for them just an indentation in the ground where they should have been . but once again thank you to everyone for the tips , very much appreciated .
