I feel like a contestant in one of those TV quiz shows, and not a very good contestant at that <grin>. That restriction makes life a tad more complex! Help!
In the 1939 register the woman in question is living with someone with a very similar name and identical birthdate to my father's brother. I don't see how she could also be living with someone called Palmer?
Or, if we are talking about my father's sister, then I can't find a matching record with the correct birth date living with Palmer.
I'm sorry, I need another clue please ...
The parents of Arthur, Ellen, & John were: Thomas William Parr 1867 and Edith Louise Tidy 1873. I can find them in the 1901 census but not in the 1911.
