When you start getting to the level of information not actually on the grave marker, not to mention information about people known to be buried in the cemetery, but whose grave markers are missing or no longer legible, it makes sense to have this information in a separate database rather than in OSM itself.  I am on the board of a small historical society that maintains an old cemetery.  Many of the graves once had cypress-wood markers, as the local stone doesn't weather well, and marble or metal markers were expensive. An early-twentieth-century grass fire destroyed the wooden markers, so we now don't know exactly whom is in the majority of the graves.
