That is the incredible possibility raised about Unity Mitford – an English aristocrat who was infatuated with the Fuhrer.
Torn between love for her homeland and dedication to Hitler, Unity – who was 25 and living in Munich at the time – shot herself in the head when Britain declared war on Germany in 1939.
She is then said to have lived as an invalid with her mother in the Cotswolds, moved to a Scottish island in 1944 and died as a result of her brain injury aged 33 in 1948.
But Martin Bright, writing in New Statesman magazine, has told of a phone call from a woman called Val Hann, suggesting more of a story.
“Her aunt, Betty Norton, had run a maternity home in Oxfordshire during the war and said that Unity Mitford had been one of her clients,” wrote Bright.
“Her aunt’s business, in the tiny village of Wigginton, had depended on discretion and she had told no one except her sister that Unity had a baby. Her sister had passed the story on to her daughter, Val.”
