"Françoise Athénaïs de Rochechouart de Mortemart, marquise of Montespan (5 October 1641 – 27 May 1707), better known as Madame de Montespan, was the most celebrated maîtresse en titre of King Louis XIV of France, by whom she had seven children."

If these portraits and descriptions about her looks are anything to go by, several of her descendants do actually resemble her in some strange way. I'll skip several generations here and only pick some of her descendants (because there are so many and not all of them look like her). Let's take a look:
The late Princess Joséphine Charlotte of Belgium, Grand Duchess consort of Luxembourg and her son, the current Grand Duke Henri


Henri's children (sorry, I was too tired to look for recent pics) Guillaume, Felix, Louis, Alexandra and Sebastien:





I didn't see much resemblance with the Belgians but now that I think about it... Prince Amedeo
