Looking for Vietman/American child. Mother married George EW Fritsche "Buddy"

I am searching for the wife and child of Buddy Fritsche. His name was George Ernst Walter Fritsche Jr. The family called him Buddy. He served one year in Vietnam. He entered the Army Feb. 1967 and on to Vietnam in Aug. 1967. He met and married and I believe had a Son. Not real sure. He never sent for them because after he returned home he was killed in a car wreck. Any help in finding them would be appreciated. Please email me at lauranick@wcnet.net or laurajthf@yahoo.com Thanks, Laura Fritsche
