Wigginton is a village and civil parish about 6 miles (10 km) southwest of Banbury in Oxfordshire. The village is beside the River Swere, which forms the southern boundary of the parish. A Channel Four documentary, Hitler's British Girl, investigated the possibility that Unity Mitford gave birth to the son of Adolf Hitler in Hill View Cottage, Wigginton.

Unity Valkyrie Freeman-Mitford was a British socialite known for her relationship with Adolf Hitler. Both in Great Britain and Germany, she was a prominent supporter of Nazism, fascism and antisemitism, and belonged to Hitler's inner circle of friends. After the declaration of World War II, she attempted suicide in Munich by shooting herself in the head. She survived but was badly injured. She was allowed safe passage back to England but never recovered from the extensive brain damage; she later died from meningitis related to the bullet lodged in her head.
