Maria Lackfi
Maria Lackfi (died before 1343) was the first wife of Nicholas Alexander, voivode of Wallachia, and probably came from a Bosnian or Balkan Orthodox elite family.
She was the mother of Vladislav I, called Vlaicu, who ruled Wallachia from 1364, of Voislav (died 1366), and of Elisabeth (died 1370), who married Ladislaus of Opole. She was probably buried at Câmpulung.
