Send a message to the person who requested a photo of the grave monument of John Curnow with the following comment:
This is the first actual proof I have, other than paper certificates of my family. John Curnow was the younger brother of my great great grandmother Catherine. I haven't been able to find her grave where she was buried here in Penzance. John was also mentioned on the death certificate of his father Thomas Curnow, my great great great grandfather.
