Send a message to the person who requested a photo of the grave monument of Henry John with the following comment:
I have just come across your website. My ancestors originate in Cornwall and St Just. It is very informative and appreciated. I am located in Victoria, Australia, and have limited access to headstones and a quick glance of your records reveals I am related to 90% of them. If I can be of assistance from this side of the world I would be happy to help
