Back in 2022 I wondered about an Audrey Allis who had been a contact in a cyclists magazine around the WW2 years.
After doing a little research it seems the mystery is solved and this was found to be a pen name for the person concerned. She was indeed a niece of "ragged staff" through his marriage to Ann Palmer, and used her first two Christian names of Audrey Alice to become Audrey Allis.
It really seems to be that simple.
