In 1691, during one of his visits to the German Quarter, young Peter I of Russia became enamoured of Anna Mons, the daughter of Dutch wine merchant Johan Mons. It is generally thought he was from Westfalia. Her younger brother was Willem Mons (1688–1724), destined to be the Imperial Chamberlain to Catherine Ist and Matrena her sister who married Fedor Balk, Major General and Governor of Riga. Her niece was the infamous Natalia Lopukhina (1699–1763) later victim of the so-called Lopukhina Affair in 1742. As his relations with the tsarina Eudoxia Lopukhina gradually worsened, Anna Mons took the place as his permanent and semi-official royal mistress. In the 1690s, he gave her 295 farms and a mansion near Moscow. The relationship lasted for 12 years.
Prison and death
After Peter divorced Lopukhina, Anna had ambitions of marrying Peter herself, but by 1703 she feared he had lost interest in her and took up a flirtation with the Prussian ambassador Keyserling to rekindle Peter's affections. Keyserling proposed marriage, provoking Peter to have Anna expelled from her estate and throw her in prison along with her mother, sister and thirty friends. Peter later allowed the two of them to marry, which they did in 1711. Anna died three years later of consumption.
In 1707, Peter I did marry again, to Marta Helena Skowrońska who dyed her hair black so she would not resemble Anna Mons. She later became Catherine I of Russia in 1712. Anna's younger brother, Willem Mons, became the Secretary and friends with Catherine. He was an old friend of Peter's, having taken part in the battle of Poltava. He was charged and executed for abusing his access to the Empress along with his sister Matrena, who was beaten and exiled to Tobolsk, Siberia, however her husband was given permission to remarry. The night before the execution Peter told Willem he was sorry to lose such a talented man but he had to execute him. The two were accepting bribes for their influence, according to the favor asked and position of the petitioner, despite having wealth and property laid on them due to their positions. Matrena was later restored to favor by Catherine after the death of Peter, her brother's head in alcohol was put on display in a museum, originally the summer palace of the Tsar and is on display to the present.
