No Mary Alice with the correct birth date has been found in Blackburn in the 1939 Register. There are eight possible marriages in Blackburn, but most of these couples cannot be found in the 1939 Register in Blackburn, so she could have married and moved away.
Alternatively she may have died young (after 1911), but there are no good candidate records of this in Blackburn under her maiden name.
A possible probate record for her father, dated 24 Jan 1944, identifies a Mary RILEY, spinster, as his legatee.
