Good luck in finding whatyou seek.
If you cannot find what you seek online then my tale may help.
I had to go into Bradford Archives to personally look up microfische records as they are not yet digitised and I was successful for finding all six grave id’s. We went in person as the Archive wanted to charge a search fee for each enquiry.
The next problem was actually finding them in the graveyard which was huge and as the zonal and numbering proved to be add hoc with at least three section H unconsecrated scattered and the numbering system was not continuous. I had this problem as the Archives did not have a map of the cemetary, but I found one eventually online and will revisit when next in that City. A notice in the graveyard stated that family researchers would be charged if they went to the graveyard office to ask for help, as it was the office was closed when we visited. So please bear this in mind.
In another grave search I found the grave image on the Find a Grave website, as we just happened to be in the Town concerned I thought I would pay respects but did not go armed with anything other than the image but finding the grave was impossible since the graveyard was totally overgrown and I mean overgrown.
So if you intend to visit the grave go armed with section and plot numbers together with a plan of the graveyard. Whilst not on every headstone you should find a number engraved probably low right, this is the plot number so you can work out precisely where the grave in question is. Btw not all graves have headstones.
Manchester Southern Cemetary by contrast were brilliant, they physically took us to the two graves we went to see and wanted nothing but our thanks.
Hope this helps.
