Send a message to the person who requested a photo of the grave monument of Peter Kettlewell with the following comment:
Peter Kettlewell is one of my ancestors (no real surprise as we share the same name). If I have got my records correct then he is my Great, great grand uncle. I would be most grateful if you would send me images of the headstones so that I can verify what I think are family connections. I deplore the fact that only 50% of people you have helped have actually sent you an acknowledgement. I will be sure to reply to your e-mail. Many thanks Peter
