I do not have any more information on Lillian B Blum than you do. But my maiden name is Blum. I may be related to Lillian's father William W. Blum...of course then I would be related to Lillian and you also.
Do you have any information on William W. Blum? Do you know his parents' names?
I have a few photos of a Lillian Blum...a young woman probably single at the time. If you email me at firstname.lastname@example.org
...I will send you copies. Maybe we are family? Annette Vliet nee Blum
