My father purchased this book when he returned home. I've never really researched Iwo as it was too personal. When I get home I'll use this new info to see if your cousin might be listed as one of the support units on Iwo. You might contact a historian in the Marine Corps. I had a name of someone at Quantico but lost it. Also, search the internet for Marine histories. Some of the pages on Iwo jima will bring tears!
