Who married Albert III, Duke of Bavaria?

Albert III the Pious of Bavaria-Munich (German: Albrecht III. der Fromme, Herzog von Bayern-München; 27 March 1401 – 29 February 1460), was Duke of Bavaria-Munich from 1438 to 1460. He was the son of Ernest, Duke of Bavaria and Elisabetta Visconti, daughter of Bernabò Visconti.

Agnes Bernauer (c. 1410 – 12 October 1435) was the mistress and perhaps also the first wife of Albert, later Albert III, Duke of Bavaria. Because his father, Ernest, ruling Duke of Bavaria at the time, considered this liaison with a commoner unbefitting his son's social standing, he clashed with his son over the matter and finally arranged to have Agnes condemned for witchcraft and drowned in the Danube in 1435. Her life and death have been depicted in numerous literary works, the most well known being Friedrich Hebbel's tragedy of the same name and the folk musical Die Bernauerin by the composer Carl Orff.

Anna of Brunswick-Grubenhagen-Einbeck (1414 – 4 April 1474) was a daughter of Duke Eric I of Brunswick-Grubenhagen and his wife, Elisabeth of Brunswick-Göttingen, daughter of Otto I, Duke of Brunswick-Göttingen.

Anna's first marriage was with Duke Albert III of Bavaria. They had the following children:

• John IV (1437–1463), Duke of Bavaria
• Ernest (1438–1460)
• Sigismund of Bavaria (1439–1501)
• Albert (1440–1445)
• Margaretha (1442–1479), married in 1463 with Marquess Frederick I of Mantua
• Elisabeth (1443–1484), married in 1460 with Elector Ernest of Saxony (1441–1486)
• Albert IV (1447–1508)
• Christopher (1449–1493)
• Wolfgang (1451–1514)
• Barbara, a nun in Munich

After Albert's death, she married Duke Frederick III of Brunswick-Calenberg-Göttingen. This marriage remained childless.
