Send a message to the person who requested a photo of the grave monument of Robert Bulmer with the following comment:
Robert and Mary Bulmer are very likely my 4 times great grandparents. From the picture, it appears that their gravestone is practically touching the stones of their son (John) and grandsons (Robert, John and James), so they are most likely my relations. They would be my father's father's father's mother's father's parents.
