Send a message to the person who requested a photo of the grave monument of William Cowley with the following comment:
My direct line goes back to the Cowleys and Bsrkers of Ashover, but I don't have this person recorded, and if he fits he would be the farthest back I've managed to trace the line. I'm about to get involved in a similar enterprise to yours, and one of my concerns is being contacted by demanding and ungrateful people, so you'll definitely get an acknowledgement from me! Keep up the good work.
