Send a message to the person who requested a photo of the grave monument of William Twysden with the following comment:
Hi, I'm completing John Twysden's profile on Wikitree and would like to be able to cross match the image against the transcription, to see for myself. Also, if possible, may I have permission to display the photo on his wikitree page? If copyright doesn't permit, I understand. Thank you for providing the information on the GPS page.
