Ady,
I have just received the death certificate for David Williams. It states he was 2d Battallion RWF and was aged 35 when he was killed - which ties in with my David. No other clues other than he was born in Wales on it. I think the only other option is for me to somehow send for his records. Would that have to be done through my father as he is a great nephew to David? I am also going to contact the local Council where the War Memorial is situated to see if I can get any clues from them, probably not but worth a try. I've got the bug to find out more now.
Best wishes
Nerys
