Life

Born in Bayreuth, she was her parents' fifth child. Her maternal grandparents were Albert Frederick, Duke of Prussia, and Marie Eleonore of Cleves. One of her maternal aunts was Duchess Anna of Prussia. She had three surviving siblings: Anna Maria (1609–1680), wife of Prince Johann Anton I von Eggenberg, Duke of Krumlov; Erdmann August (1615–1651); and George Albert (1619–1666).

She was married to John George, Prince Elector of Saxony, on 13 November 1638 in Dresden.^[2] He was her first cousin, being the son of her maternal aunt and namesake, Magdalene Sibylle of Prussia. Her sister-in-law and cousin was Magdalene Sibylle of Saxony.

In 1680 she was widowed and retired to Freiberg-Colditz.
