Susan Hayward ( old time actress ) some how on my dad's side of the family.

And Hitler only had a sister . There were other siblings from his fathers third marriage but only Hitler and his sister lived.

He would have had a step brother Alois Jr I think but he was from his fathers second marriage.

I know, creepy I know about Hitler but I was obessed with him when I was in middle and high school. I studied a good deal about him.
