44th Infantry Division
I called a member of the division's veterans association, who put me in touch with another member, who put me in touch with a guy who served with the 114th Infantry in France and Germany during the war. Several years ago, this guy hit on the idea of tracing all those, living and deceased, who had served with his company during the war. He later expanded it to include his regiment, then the entire division. He now has a data bank containing info on over 22,000 who have served with the division.
