Send a message to the person who requested a photo of the grave monument of Lavinia Passman with the following comment:
Thomas and Lavinia (nee Boyes) were my late grandfather's grandparents. I think I may have requested an image previously but cannot find any record of receiving it - apologies if it was sent already or if there was a reason that you didn't send (I do have ones I requested in 2011, and of my emails thanks you for sending, but nothing since).Thanks and best regardsMark
