I am trying to find out information about by Uncle Bill - William Everest. I know very little about him but understand that he was a rear gunner on a Lancaster bomber which was shot down somewhere over Holland. I am fairly certain that he was in the Dam Buster Squadron, but know no more than that. He was my Father's younger brother and all of his generation are now daed. I now have 3 sons and would very much like them to know something of my Uncle Bill. Can anyone help me to find out what happened to him?
