As I’ve come to learn was that Hitler had an older brother who ran away due to his abusive father. Did his brother make it to the 30s and see his younger brother’s rise to power or did he die after he ran away?
ALois Jr. really didn't have much to say. He left pretty little of his thoughts and mostly tried to keep out of it, as he lived in the UK for a time, had an irish first wife, and a son who... didn't like Hitler! His son William Patrick Hitler though was a vocal opponent of his uncle and served in the US Navy during the war. I've written more about the extended family of Adolf Here and here which may be of interest.
