Those of us who met the late Archduke Otto von Habsburg (1912-2011) and shook his hand, must have realized that they had been only 4 handshakes away from meeting Marie Antoinette... She met her nephew, the future Emperor Francisc II of Austria, while he was young, who later shook the hand of his grandson, the future Emperor Franz Joseph I (who was 5 when Francisc died), who later shook the hand of Archduke Otto (who was 4 when Franz Joseph died). Those who may meet Otto's children would be only 5 handshakes away from meeting Marie Antoinette...
