I'd contact a local or national veterans' affairs assoc. and ask how to reach former members of that bomb group. They would know about your cousin. And ask any group of Airmen that attend reunions and events. Charlene McGee Smith wrote an excellent book about her dah Charles, a Maryland resident who is very active with the guys.
