Konstantin stayed for a few days at Alexandra’s father’s castle. His visit there had been arranged by Alexandra’s aunt, Grand Duchess Elena Pavlovna, who had been born Princess Charlotte of Württemberg. Elena and Alexandra's mother were both descended from Frederick II Eugene, Duke of Württemberg. Elena was married to Grand Duke Michael Pavlovich, the younger brother of Tsar Nicholas I. Elena Pavlovna was therefore Konstantin’s aunt by marriage and Alexandra’s aunt by birth. Elena was a strong influence over Konstantin, who admired her intellect and progressive views. She had literary interests and was musical, founding the St Petersburg Conservatoire, and the young Konstantin often spent time at Elena's home and salon in St Petersburg.
