She alleged that the family name had originally been ‘von Hohenzollern’, for they had emanated from the Hohenzollern district of the Holy Roman Empire. A certain George von Hohenzollern had, she said, fought on the side of Archduke Ferdinand of Austria at the Siege of Vienna in 1529. He had shown great daring in leading an unofficial raid against the Turks and capturing the Sultan’s standard. This (said Aunt Grace) was why he was given the nickname Tollkühn, ‘foolhardy’; and the name stuck.
