Does anyone know about the layout of St Francis Xavier Cemetery in Weymouth?

I have been trying to contact the cemetery office to find where Timothy and Margaret Sullivan are buried. Unfortunately, I have not been able to get in touch with anyone.

Timothy was buried in 1929 and I suppose he was the first buried in the plot.

What part of the cemetery was being sold around 1929. I'll have to search stone by stone to see if I can find them. If I knew where to start it would be easier.
