There were 2 George E. Donahues that were KIA in WWII that served in the US Army . One was a Flight Officer, the other a PVT. Here is the information for the Pvt. I am assuming this is probably him. If he was the Fight offier let me know and I can send you that information.

You can find instructions on how to use this information write for his IDPF at message # 2112 on this forum.
