A lot of their early history in WWII is told in this magnificent book:
Thanks for the link to the book. My Grandma's brother was with the 34th; he spent the last two years of the war as a "guest" in Germany after being captured at Anzio. We have some newspaper articles from when he returned (he described the camp, guards, etc.), the original "MIA" telegram, and some photos from N. Africa.
I think I will pick up the book for some additional stories.
the author is from Pennsylvania though.
