Héder (Hederic or Hedrich) was born into the Hédervár branch of the powerful gens (clan) Héder, as the son of Denis (I). His grandfather was Héder, namesake co-founder of the clan.[1] He had a brother Denis (II), progenitor of the prestigious Hédervári family.[1]
The name of Héder (II) first appears in contemporary records in 1210, when he is mentioned among the neighbors, when royal officials determined the borders of the estate Novák in Győr County. At that time, he possessed Hédervár. Sometime between 1221 and 1223, Héder was appointed ispán of Győr County, according to a royal charter issued in 1223. This is the last information about Héder. The next known office-holder Simon Nagymartoni is first mentioned in this capacity in 1232.
From his unidentified wife, Héder had two sons, James I and Lawrence III, and a daughter, who married Pousa Bár-Kalán. In 1255, James and Lawrence successfully recovered their sister's dowry from the late Pousa's son, Nana.
