Unity Valkyrie Freeman-Mitford (8 August 1914 – 28 May 1948) was an English socialite best known as a devotee of Adolf Hitler. Both in Britain and Germany, she was a prominent supporter of Nazism and fascism, and formed part of Hitler's inner circle of friends. Following the declaration of World War II, Mitford attempted suicide in Munich, and was officially allowed safe passage back to England in her invalid condition, but never recovered.
Unity was a member of the Mitford family, tracing its origins in Northumberland back to the 11th century Norman settlement of England. Her sister Diana was married to Oswald Mosley, leader of the British Union of Fascists. SOURCE: Wikipedia
