Mr. Salden can order Sergeant James W. Du Laney's deceased file, as well as those of any others interred at Margraten in which he may be interested.
You'll find instructions at Message #2112, this forum (go back to the Main Page, enter "2112" in the box in the upper corner of the page marked "Jump to #____" then click on "Go"). You may want to make a print-out of the message and pass it along to him.
Ironically, there's a Private First Class James W. Dulaney, 33 632 839, Army of the United States, buried at American Battle Monuments Commission Manila Cemetery, Fort Bonafacio, Luzon, Philippines. PFC Dulaney was also killed in March 1945. He was assigned to General MacArthur's Headquarters when he was killed in action on 5 March 1945 during the liberation of the Philippines.
(P. S. I mailed a request for William Long's deceased file with your return address. They may be reluctant to send it International Mail so if you don't hear anything in a month or so, e-mail me and I'll take care of it.)
