Huh? I think all the efforts have been to help with the totality of records and that was why there were suggestions about looking at other contemporaneous files for extra help. No-one on this thread ever suggested that the AIF files were added to by Red Cross, just other places to look.
OP has not commented on if they are looking at the blended personal eg file base plus the one that was carried with the group. Not sure what the Aus practice was but the NZ practice, from looking at 3-4 of them, was that they were just added, ie no attempt was made to blend the two files.
The view that NOK are always advised first is not correct, how could it be? My dad and his brothers knew before their mother who was NOK that their sibling was missing in action but not presumed dead, in fact he was only presumed dead in the 1950s after two searcher parties had gone to Crete from NZ after the war.
The tips by others are like gold, I for one do not want to impede this practice as I want to have all the ideas possible when I put requests up......I don't want people to be put off by the rather ungracious reception that this OP has given.
We are not all like that and most of us welcome all the reckons, ideas, tips or off the wall ideas that you might have. Not one of us has the sum total of knowledge of these ancestors of ours.
EDIT, not worth it.....the general points remain
