Aigusta Anastasia of Lithuania

Aigusta Anastasia (c. 1320–1345), most likely a daughter of Lithuania's Grand Duke Gediminas, was baptized Orthodox as Anastasia to marry Prince Simeon of Moscow in 1333. The match promised better relations between them, but war resumed in 1335.

Her sons died in infancy, and her daughter Vasilisa married Prince Mikhail Vasilevich of Kashin in 1350. She took the veil shortly before her death on 11 March 1345 and was buried in a Kremlin church she had founded.
