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 Howard
When Catherine's parents married, her mother already had five children from her first husband, Ralph Leigh ( – 1509); she went on to have another six with Catherine's father, Catherine being about her mother's tenth child. With little to sustain the family, her father was often reduced to begging for handouts from his more affluent relatives. After Catherine's mother died in 1528, her father married twice more. In 1531 he was appointed Controller of Calais. He was dismissed from his post in 1539, and died in March 1539. Catherine was the third of Henry VIII's wives to have been a member of the English nobility or gentry; Catherine of Aragon and Anne of Cleves were from continental Europe.
