This particular map is unique: Astrié notes both the locator number as well as the page number in his text for 405 burial sites.
He uses a complicated, and, I think, confusing system of numbering the divisions. He refers to massif or “clumps” of graves within a division system that is unique to his book.
The cemetery layout he illustrates, however, does resemble the present layout so figuring out grave locations isn’t terribly difficult.
