Sophie of Schwarzburg-Blankenburg

Sophie of Schwarzburg-Blankenburg was the daughter of Count Gunther IX, who was elected anti-king against Charles IV in January 1349 and died at Frankfurt that June, and Elizabeth of Hohnstein. In November 1353 she married Count George of Kafernburg, a union dissolved despite a papal dispensation.

Before November 1357 she married Frederick of Orlamunde-Lauenstein, later Count Henry XI of Stolberg, and finally John II of Schwarzburg-Wachsenburg. She is last documented in 1394 and 1395.
