During my last “genealogy” visits to this cemetery (before the pandemic, two years ago) and over the past 35 I don't know any map, or even plaques dividing the cemetery into certain sectors, groups etc. The entries in the book of burials I scanned are often even entries of the type “old cemetery”, “new cemetery”, which do not correspond to any plaques and divisions in the cemetery.
Luckily, The cemetery is run by very friendly people, friendly and willing to help people. All you have to do is visit them on any day (preferably during the week)., do 12:00) and either meet in person or call the telephone number on the front door (the building in the central part of the cemetery). I'm sure, that unless they have ten burials at the same time, they will certainly indicate the exact location of the grave.
