cemetery under water?

Even if the coordinates shown by Find A Grave and on Google place the cemetery in a body of water, it doesn't necessarily mean that's exactly where it is (even though we consider Find A Grave generally authoritative, it isn't a perfect resource, and their marked locations aren't always accurate, which is why we recommend cross-referencing multiple sources). So unless you found authoritative information/evidence explaining that a cemetery was inundated or destroyed, then it's best to assume it still exists. It’s extremely rare that you’ll need to delete a cemetery point, so if you can’t find evidence that a cemetery has been destroyed, inundated, or its burials disinterred (or that it’s a duplicate), it’s best to leave the points on the map and move on to points you can confirm.

It looks like you already edited a point representing a Draper Cemetery (aka, Draper Duckworth Martin Cemetery?). The current location of this point matches with a location marked on the Historical Topo layer, so until you are able to track down more affirmative location information, you can leave the point where it is.
