Peter III of Russia
Empress Elizabeth arranged for Peter to marry his second cousin, Sophia Augusta Frederica (later Catherine the Great), daughter of Christian August, Prince of Anhalt-Zerbst and Johanna Elisabeth of Holstein-Gottorp. The young princess formally converted to Russian Orthodoxy and took the name Ekaterina Alexeievna (i.e., Catherine). They married on 21 August 1745. The marriage was not a happy one but produced one son, the future Emperor Paul, and one daughter, Anna Petrovna (20 December 1757 – 19 March 1759). Catherine later claimed that Paul was not fathered by Peter: that, in fact, they had never consummated the marriage. During the sixteen years of their residence in Oranienbaum, Catherine took numerous lovers, while her husband did the same in the beginning.
Catherine of Aragon
Catherine has remained a popular biographical subject to the present day. The American historian Garrett Mattingly was the author of a popular biography "Katherine of Aragon" in 1942. In 1966, Catherine and her many supporters at court were the subjects of "Catherine of Aragon and her Friends", a biography by John E. Paul. In 1967, Mary M. Luke wrote the first book of her Tudor trilogy, "Catherine the Queen" which portrayed her and the controversial era of English history through which she lived.Her baptismal name was "Catalina", but "Katherine" was soon the accepted form in England after her marriage to Arthur. Catherine herself signed her name "Katherine", "Katherina", "Katharine" and sometimes "Katharina". In a letter to her, Arthur, her husband, addressed her as "Princess Katerine". Her daughter Queen Mary I called her "Quene Kateryn", in her will. Rarely were names, particularly first names, written in an exact manner during the sixteenth century and it is evident from Catherine's own letters that she endorsed different variations.
Loveknots built into his various palaces by her husband, Henry VIII, display the initials "H & K", as do other items belonging to Henry and Catherine, including gold goblets, a gold salt cellar, basins of gold, and candlesticks. Her tomb in Peterborough Cathedral is marked "Katharine Queen of England".
