I am busy writing a book about Frank Harris and his biographers, so updates here may be limited for a while.
In that connection, if anyone has any information about Rosa Gabrielle Bain 1901[?]-1980 aka "Linda Morgan Bain" aka "Rosa Gabrielle Wells" aka "Rosa De Leon", I'd be much obliged. As Rosa De Leon she owned and ran the Amersham Playhouse with her husband(?) John Ferris. See http://amershamhistory.info/research/sport-entertainment/amersham-playhouse-1949-56/
