Sir: I tried to find an Association for the 397th . The best I could come up with is the address for the 100th Infantry Association. Mr. Rudy P. Keserich 700N. Bruce Lane Glenwood,Il 60425 708-754-7730
The 100th Division also maintains a web page for their association on line. Go to any good search engine and type iin 100th Infantry Division. I myself use Google. I also have the 100th Infantry Division Pictorial Review printed in 1944. It shows the pictures of everyone in the division. Another spot you might try is anywho.com and type in their name and last known state, see what comes up.
