Wilhelmina Maria Frederica of Rochlitz

Wilhelmina Maria Frederica, Countess of Rochlitz was a Polish noblewoman of German descent. She was the illegitimate daughter of John George IV, Elector of Saxony, and Magdalene Sibylle, Countess of Rochlitz, his official mistress. Her parents, who may have been half-siblings, both died from smallpox soon after her birth, and she was raised in Poland at the royal court of her uncle and guardian, Augustus II the Strong of Poland.
