It seems that we have too many unknowns and unfortunately a very common name. You originally said the date was around April 1942 so presumably a death in 1943 is far too late? In your post #13 you say "he was likely to have been a prisoner of War", so perhaps not necessarily the case? Do you know for a fact he was Army, could he have been Navy? You have all the information necessary to apply for his service records, name & date of birth, so why not go ahead and order them? It will take some time but if you are interested in the facts that may be the only way. You do not need a death certificate if KIA, quote from application "A copy of the service person’s death certificate if the individual died following discharge from the service." He didn't.
