ใครแต่งงานกับAnna, Grand Duchess of Lithuania?

Anna or Ona Vytautienė (died on 31 July 1418 in Trakai) was Grand Duchess of Lithuania (1392–1418). She probably was the first wife of Vytautas the Great, Grand Duke of Lithuania. Anna was mother of Sophia of Lithuania, the wife of Vasily I of Moscow. She is best remembered for helping Vytautas to escape from a prison in Kreva in 1382 and thus probably saving his life. Little is known about Anna's life and even her origins remain disputed by historians.

Vytautas the Great (; c. 1350 – 27 October 1430) was a ruler of the Grand Duchy of Lithuania. He was also the prince of Grodno (1370–1382), prince of Lutsk (1387–1389), and the postulated king of the Hussites.

In modern Lithuania, Vytautas is revered as a national hero and was an important figure in the national rebirth in the 19th century. Vytautas is a popular male given name in Lithuania. In commemoration of the 500-year anniversary of his death, Vytautas Magnus University was named after him. Monuments in his honour were built in many towns in independent Lithuania during the interwar period from 1918 to 1939. Vytautas knew and spoke the Lithuanian language with his cousin Jogaila.
