I know Lillian married a man much older than she was-- probably for economic reasons -- The marriage according to what my grandmother said, was not a happy one-- but in those days people did not divorce--
I will ask my mother if she knows anything about Lillian having had a child-- I am not aware of one, but often people did not talk about such things back then--

Do you know where your mother was born or have any documentation that might help? Would be wonderful to find a missing branch of our family--
