My mother and aunts never mentioned any other children or marriages. I know the daley house was not a pleasant one. The father was abusive. I know that, in my mother's case at least, an orphanage then foster homes were where she grew up. I was lucky to have met two of my mother's sisters and one brother. Unfortunately, I believe the sisters and brothers that she knew are all deceased. We'll probably never know their true history. Good luck to you.
