 Historians of the 15th and 16th centuries , with perspectives that were either against or in favour of the family , wrote differing reports of the family 's status before King Sigismund 's grant . Jan Długosz described John Hunyadi as " a man of unknown origin " , and he is likewise mentioned as " a Vlach by birth , not highly born " by Aeneas Silvius Piccolomini . On the other hand , Johannes de Thurocz said that John Hunyadi " was descended from a noble and renowned race of Wallachia " .
