I had read that the Nazis killed 10,000 people in all manner of brutal methods in retribution, wiping out entire families, so I was surprised to hear that van Staffenburg's widow had survived for more than a few days, much less 62 years!
--ditto--I was under the impression all the family were killed, also--
Stauffenberg had married Nina Baroness (Freiherrin) von Lerchenfeld on 1933-11-26 in Bamberg. They had five children: Berthold, Heimeran, Franz-Ludwig, Valerie and Konstanze. She was interned in a concentration camp after her husband's execution. She died aged 93 on 2006-04-02 near Bamberg. The eldest son, Berthold, became a general in West Germany's new army, the Bundeswehr.
His widow Nina described her late husband thus:
"He let things come to him, and then he made up his mind ... one of his characteristics was that he really enjoyed playing the devil's advocate. Conservatives were convinced that he was a ferocious Nazi, and ferocious Nazis were convinced he was an unreconstructed conservative. He was neither."
