Unity Mitford and Adolf Hitler's son

Did Adolf Hitler have a son? The Times of London published an interesting story today about Unity Mitford, who may have been mother to Hitler's child. This is extremely doubtful. Mitford, interestingly enough, was a cousin of Winston Churchill, and went to Germany in the early 1930s, according to the article, and found herself in Hitler's inner circle. The Times is referencing an article in the New Statesman.

Excerpts from the Times:

She first went to Germany in the early 1930s, when the Nazis were on the rise, and the young woman was so overwhelmed by a visit to the Nuremberg rallies that she became determined to meet Hitler. This she managed in spectacular style, ingratiating herself to the point where he described her to friends as “a perfect specimen of Aryan womanhood”.

[...]

The makers of a forthcoming Channel 4 documentary, Hitler’s British Girl, examined theories surrounding Mitford’s notorious life and concluded that there was very little evidence that she was pregnant or ever had a sexual relationship with Hitler.

Whereas some might consider the idea of her giving birth to the Führer’s only offspring to be a harmless and intriguing tale, Richard Evans, Professor of Modern History at the University of Cambridge, thinks differently. “Unity Mitford’s relationship with Hitler was basically political,” he said. “She was a hard-line Nazi and a rabid racist and antiSemite, and I’m worried that gossip about her personal life might take attention away from these facts.”

And from the New Statesman:

At this point I decided to return to the National Archives, where I discovered a file on Unity that had been sealed under the "100-year rule" - reserved for only the highest classification of top-secret files. An official told me that it was possible to have the classification of such files reviewed and I applied to have the file opened. To my great surprise, the Home Office agreed. Inside was a startling new piece of information: it wasn't quite the birth certificate of a child, but here was hard evidence that Unity might not have been quite the invalid it was supposed.

After all these years, this is still fascinating stuff.
