I wonder what kind of compulsion there was at the time for everyone to complete these forms?
I have drawn a blank with both sets of grandparents and quite a few others. A friend has looked as well - nothing.
Very, very disappointing.
I don't think they were given ration books if forms were not completed or names not included. I believe many people were known to have excluded sons in the hope that they weren't called up but soon realised they'd face other problems and had to get the forms amended.
On the other hand, if their names were all wrong on the Register, as so many of them are, their ration books would also have had their names wrong, and I would have thought that would have created problems too. I will ask my mum tonight if her ration book was in her own proper name because on the Register her parents' surnames are completely wrong. She was 18 and living at home at the time and has been redacted.
UPDATE: I talked to my mum this evening, who is quite competent, and she says her ration book was in her correct name. She still has it somewhere, and that is the way I remember it too, having seen it years ago. So I guess the problem with the Register is in the transcription.
