Working off the diagrams mentioned by Myluck I have put together the following which might be of some help in searching for graves in Goldenbridge.
Richard, our tour guide, stated that the cemetery was laid out in grid form with each grave identified by a ‘column letter’ and a ‘row number’.
Using
THIS OSI map I will hopefully describe the lettering and numbering system used.
On entering the cemetery the lettering from the gate runs along the east boundary wall from right to left and the numbering on the north wall runs from left to right. The letters start with A then Aa then aa. It continues on through B,Bb and bb until the final three columns which are lettered CC, CCcc and cc giving a total of 87 columns in total (29 X 3). The cemetery is not a perfect square and the west wall contains six less columns than does the east finishing with the letters aa. The numbers on the north and south walls go from 1 to 50.
The only reference I have to go on is that supplied by Aussie Trekkie for the grave purchased by her GGG/father W33. I would estimate that this grave is 18 graves back from the bottom right hand corner and 15 graves in towards the chapel and marked on the map by the red +
Using the oval shape in the middle of the cemetery as a focal point and drawing four imaginary tangents running parallel to the boundary walls will divide the cemetery into nine segments.
The first three contain the columns A to Jj and rows 1 to 13, 14 to 37 and 38 to 50
The middle three commence with Column j to t with the numbers as above
The last three sections contain the same numbers, 1 – 13, 14 – 37 and 38 to 50 but because of the irregular shape the columns vary.
Section 7 U to cc
Section 8 U to bb
Section 9 U to aa
I hope this helps in some small way to narrow down your search.
