Did Peter III and Catherine the Great have any daughters?
Catherine the Great
Count Andrei Shuvalov, chamberlain to Catherine, knew the diarist James Boswell well, and Boswell reports that Shuvalov shared private information regarding the monarch's intimate affairs. Some of these rumours included that Peter took a mistress (Elizabeth Vorontsova),[12] while Catherine carried on liaisons with Sergei Saltykov,[13] Grigory Grigoryevich Orlov (1734–1783),[14][15] Alexander Vasilchikov,[16][17] Grigory Potemkin,[16][17][18][19] Stanisław August Poniatowski,[20][21] and others. She became friends with Princess Ekaterina Vorontsova-Dashkova, the sister of her husband's mistress, who introduced her to several powerful political groups that opposed her husband. Peter III's temperament became quite unbearable for those who resided in the palace. He would announce trying drills in the morning to male servants, who later joined Catherine in her room to sing and dance until late hours.[22] Catherine became pregnant with her second child, Anna, who only lived to four months, in 1759. Due to various rumours of Catherine's promiscuity, Peter was led to believe he was not the child's biological father and is known to have proclaimed, "Go to the devil!" when Catherine angrily dismissed his accusation. She thus spent much of this time alone in her own private boudoir to hide away from Peter's abrasive personality.[23]
Princess Catherine of Württemberg
Catherine was the eldest of three children born to William I of Württemberg by his third wife and cousin Pauline Therese of Württemberg. Her two siblings were Charles I of Württemberg and Augusta, Princess of Saxe-Weimar-Eisenach. She also had two half-siblings from her father's previous marriage to Catherine Pavlovna of Russia: Marie and Sophie, the future Queen consort of the Netherlands.
