Claude, I found your letter interesting because our family has recently had reunions with a half-sister and a neice - one we never knew existed - like your situation and one who was given up for adoption. You indicated that you have listed in numerous places, however, have you attempted to find his Service Records from the U.S. Army? I found my husband's grandfather with just his name and the basic time he was in the service - sometimes it works and sometimes it doesn't but I would think being stationed in a foreign base would make it easier. I did check the cemetery records of Marlboro County, SC, and there are no "Richard Gray" listings so you can at least cross that off your list. Barb
