I just found my 2nd cousin’s name - he was killed in the first three months also.....of course, I never knew him as my father is retired military and I was never back in Jackson AL very many times....but I did shed some tears when I saw his name as he was family and he was lost over there.....
I felt a twinge for a guy I didn't know, and he wasn't as closely related as your cousin, but he served with guys who knew guys I knew, from the same general area, and all were blood.
