His sister Maria Aurora of Königsmarck was later mistress to Augustus II the Strong of Poland, with whom she had the son Maurice de Saxe, the brilliant French military commander.

He is remembered as the lover of the princess, due to the large number of love letters that are now preserved at the University of Lund.

[8] It is presumed that he was murdered in Hanover at the instigation of George Louis, and that his body was disposed of in the Leine river upon which the Leineschloss is situated.

[12] Most of the letters alleged to have passed between Königsmarck and Sophia Dorothea were published by William Henry Wilkins in The Love of an Uncrowned Queen (2 parts, 1900).

The 1948 costume historical romantic film, Saraband for Dead Lovers (called Saraband in the U.S.) starring Stewart Granger, Joan Greenwood, Peter Bull, Flora Robson, and Anthony Quayle and directed by Basil Dearden is based on the story.
