Send a message to the person who requested a photo of the grave monument of William Robertson with the following comment:
I am trying to trace my paternal great grandparents, one was named William Robertson and my granny always told us that he was a minister, I wondered if any of the names on the gravestone would be a link. As my ancestors were scottish and we live in England most of my research is done on the internet. Sites like this are an invaluable resource - Thank you.
