Orbász (also Orbas or Vrbas) was born into the gens (clan) Báncsa, an original settler family from Bács County (today Bač, Serbia).
The eldest one was Stephen I, an influential prelate in the mid-13th century, who became the first Hungarian cardinal in history, and the kindred reached its peak under his guidance.
It is possible Orbász had a fourth, unidentified child, parent of Cardinal Báncsa's other mentioned cousins.
[3] The earlier Hungarian historiography, based on genealogist János Karácsonyi's notice, considered that Orbász was first mentioned by contemporary records as a comes in 1213.
Accordingly, Stephen had established a mass-endowment for his late father's spiritual salvation and financed its operation from the income of Urkuta.
