In our rented house there is a display case in memory of a young guy who was killed in the first war. It has lots of his personal effects in it, his dog tags, his uniform buttons, cap badge, a photograph, and the letter from HM King George informing his parents that he had 'passed beyond the sight of men'.
Using the CGWC site I've found he's in the commonwealth cemetery in Fouquieres-les-Bethune, near Lens, quite close to Lille. It's not a massive way out of our way, so we'll be dropping in for an hour or so in June.
His parents lived in a house over the hill from here, but following the war they emigrated to Canada, and some of their personal effects were kepy by my landlords father, to be sent on when they were requested.
They were never requested, and I wonder how many visitors he's had in the last 90 years. (Well, it'll be 90 years to the day on Monday)
