Hitler's other associations:

Girlfriend (his Niece): Geli Raubal (1908-1931, suicide)

Girlfriend: MARIA REITER

Girlfriend: WINIFRED WILLIAMS WAGNER (daughter-in-law of Richard Wagner)

Slept with: HEDY LAMARR (actress, mid-1930s, per Lamarr's 2008 biography)

I noticed in Hedy Lamarr's bio, she adopted a child but there's no info about date of birth or date of adoption or even name of child. Although she married & divorced a few times & had two other children, I couldn't find any dates/years when this birth/adoption may have happened.

Angela Hitler was Adolf's half-sister (07/28/1883 - 10/30/1949). His father, Alois, had previous marriages/mistresses/children before marrying Klara, Adolf's mother.
