any info on my Grandfather (96th Bomb Group)

This is my 1st post as I am just starting out on researching my Grandfather.
His name was Rosario Lizzio and he was the top turret gunner on B-17 "Marzidoats" 3rd Air Division, 45th Bomb Wing, 96th Bomb Group,338th Squadron, Bomb Squadron code "BX". His pilots name was "Lawson". He was stationed at Snetterton from April 1944 until he completed 31 missions in Sept. 1944.
My mom had done some research in the early 90's after her dad had passed and actually exchanged letters with one of the side gunners "Joe Yantz" who provided some stories but she never got any info on bombing missions, dates etc., She was also in contact via e-mail (found from this web-site) in 2002 with a fellow in San Francisco who I believe had a copy of "Snetterton Falcons" and provided her with a complete list of the crew but no mission info. Any help would be greatly appreciated !
