As her record is not in the surviving 7000 QMAAC/WAAC files, there is nowhere else that the information would be found. The only tiny chance of finding anything else is within the Imperial War Museum's 'Women, War and Society' collection. It needs to be accessed at the IWM, and is fully searchable via their internal online database, and although it may be unlikely for her name to show up, if she can remember some of the names of the places that she worked, it may be possible to build up a fuller picture of what she did during the war.
