I found one of the items I mentioned on the 'Priceless' set of retrospective AR Show DVDs.
Paul Atterbury, a regular visitor to the N. France battlefields was, after his tenth visit walking back to his car with a friend away from the Thiepval memorial when he suddenly felt compelled to go back in and to open the cabinet containing the books listing the names carved on the memorial. He had never done this before. He found a single namesake, 2nd Lt. L J R Atterbury. On returning home he asked his father about him and was told that the man was father's uncle and that he had his watch. Father had been named after L J R.
Atterbury was then filmed at Thiepval standing under the uncle's name, holding the watch and a photo of the man wondering if this was the link which explains why Thiepval means so much to him.
"He must have watched me come ten times, wondering why doesn't he come to visit me? And one day he made me do it."
There now remains one other strange event to be rediscovered, connecting Atterbury to the memorial.
