I have stumbled across a web site that deals with a new (at the time, 2001) book about this Group. You'll need to scroll down a bit until you see the text "Two new books."
Surprisingly, (to me), they take author Stephen Ambrose to task about errors related to this Group in his book, Band of Brothers. Mr. Ambrose has passed away but these are veterans of Normandy. It would seem that they would welcome hearing from researchers in order to get the facts out. I attempted to use the links related to that section but they did not work, so I am unsure as to what was going on. However, there are some e-mail addresses.
