What was adolf hitlers second wifes name?

i believe that it was adolf's father that was married twice not adolf though, Hitler was only married once to his long time mistress Eva braun a day befopre they both committed suicide together- he shot himself and she took a cyanide pill, some suggested he married his cousin and his neice but that was just gross! some also said that he was having a affair with his neice and because of that she killed herself, but nothing has ever been proven.
