Sgt Kenneth John Cooper R.A.F.A ( 1164825 ) was killed in action over Dusseldorf in Lancaster R5604 on the 1/8/1942. His parents were Herbert and Betsy Cooper. I am doing research on him and the aircrew that died. And details of their last mission. My past research on Lancaster R5604 has highlighted many facts. I would like to contact any living relatives so that I can share my research with them if they want it. Any help on this anyone ? Also the other aircrew. Other members of R5604 aircrew : Pilot: W/O.
