Send a message to the person who requested a photo of the grave monument of Robert Clark with the following comment:
I am researching a Mary Brown (1799-1881). I am trying to find out who here parents were. The grave says that Robert Clark was her brother, but I doubt that they were full siblings. I'd like an image of the grave to see if there is any more information regarding this (i.e. if they're half-siblings, step-siblings, siblings-in-law, etc)
