[1] By the end of the 1310s, Desiderius became an illustrious member of the royal court of Charles I of Hungary, who also supported Nicholas' social advance.
[2] According to a charter from 1330, Desiderius and Nicholas were granted the possession of Bodak in Győr County (present-day Bodíky in Slovakia) by King Ladislaus IV of Hungary.
Nicholas first appears in contemporary records in 1309, when bought a portion of the estate Fornad in Pozsony County from members of the gens (clan) Apor.

Nicholas' namesake son fought in many royal campaigns of Louis I of Hungary, thus the Hédervári family returned to the aristocratic elite two or three decades later, and remained there until their extinction in the 17th century.
