After my dad passed away last year, I am finishing his research on his fathers brother Philip DeRiggi. My father never got to know him and was very interested in his time in battle. Recently my Uncle and I found a letter written by Joseph Campolei, who was Great Uncle Philips best friend in war. I am trying to find out if he still alive and would love to get in contact with him and his family to learn more about my Great Uncle. Please know if anyone could help!
