The branches of the ancient sonorous surnames of Russia have been intricately intertwined over the centuries — and all thanks to the stormy love affairs that once happened. In a series of those romantic stories that once struck the minds of contemporaries, all the heroes and heroines broke the law. And with it — the moral principles of that time, and the dogmas of faith, and public opinion… Even the autocrat Alexander II violated the holy vow he made at his wedding to the German princess, named Maria Alexandrovna in Orthodoxy. The young princess Katenka Dolgorukova also broke the law, becoming the mistress of the Russian tsar. And — Natalia Dubelt, Pushkin's daughter, leaving her husband and three children and rushing off to Germany to her Prince Nikolai of Nassau.
