From Wikipedia:

Doamna Maria Voichiţa (1457 – 26 February 1511) was a Princess consort of Moldavia (1480 – 1511), daughter of Radu III the Handsome and a niece of Vlad the Impaler. She was regarded to have an influence upon the policy of her spouse, Prince Stephen III of Moldavia, who she married in 1478. Her son Bogdan III the One-Eyed was Voivode of Moldavia too.

She is buried in the Putna Monastery, Romania.
