S'Land what a co-incidence!
I too tried to use CWWG for finding my Uncle who was a Spitfire pilot in North Africa (operation Torch) who died on March 30th 1943.
I put his name in that we all knew him by and got nothing, eventually I just tried the surname and got three pages on the last page Bingo he was, using his second name in normal life!

PS it's a long and arduous task though!
