This maybe of use along with our maps to city cemeteries.
City Road Sections.
Found the following where the Catholic Sections are situated.
Sections V1 -V5 hold many baby communal graves known as Common Graves
Section U is predominantly graves for the very young
Section Q is generally the area where ashes are scattered
*Roman Catholic sections of the Cemetery are HH, GG, KK, LL, FF, FF1 & R6
Around many of the Section perimeters are unmarked graves usually known as "Margin or Marginal Graves" The plot or grave number/s of these "Margin" graves can vary considerably to the number of the actual section plot or grave number/s. Margin graves can hold several occupants, none of whom may be related"
