"Sophia Dorothea of Brunswick-Lüneburg-Celle (15 September 1666 – 13 November 1726) was the repudiated wife of future King George I of Great Britain. The union with her first cousin was a marriage of state, arranged by her father George William, her father-in-law the Elector of Hanover, and her mother-in-law, Electress Sophia of Hanover, first cousin of King Charles II of England. She is best remembered for her alleged affair with Count Philip Christoph von Königsmarck that led to her being imprisoned in the Castle of Ahlden for the last thirty years of her life." - (en.wikipedia.org 22.11.2021)
