Rumors of Greatness

Poniatowski.  That's the family name I'm currently researching and there's a potential tie to a well-known historical figure:  Catherine the Great!

Stanislaw August Poniatowski was romantically involved with Catherine Alexeievna (Catherine the Great).  Through her influence, Stanislaw was elected the king of Poland in 1764. 

While I believe there's enough evidence to prove that Stanislaw was not a direct ancestor of ML, if one were to go back in history far enough, perhaps one could prove that he is a distant cousin, many times removed.  I don't imagine I'll be able to conclude definitively one way or another, but it is a fun connection to ponder.
