Who dated Philip Christoph von Königsmarck?

Count Philip Christoph von Königsmarck (4 March 1665 – 2 July 1694), also spelled Philipp, was a Swedish count and soldier. He was allegedly the lover of Sophia Dorothea, Princess of Celle, the wife of Duke George Louis of Brunswick and Lüneburg, the heir presumptive of the Principality of Calenberg, later to become Elector of Hanover (as George I Louis, 1708) and King of Great Britain (as George I, 1714).

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 George, 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.

Sophia Dorothea 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.
