Send a message to the person who requested a photo of the grave monument of Everard Canham with the following comment:
Hello,This is the gravestone of a friend of mine's ancestor - who I am researching the family tree for.More than happy for potential cousins to get in touch and swap research. But if possible, please let them know they won't be getting in touch directly with the relative.This is a great website, thank you so much for creating it.Best wishes,Dora Somerville
