Also check Eielson AFB. I was stationed there in the early 70's. That also was started as part of Ladd Field in 1943. If your relative was in the Air Force after it was founded in 1947 they were probably at Eielson AFB.

Fort Wainwright and Eielson are only about 23 or 24 miles apart. Ft Wainwright, the army base, back then was almost part of Fairbanks. Someone there could tell us now.
