Conrad, son of Albős (c. 1240–1269) was ispán of Győr County and chief cellarer for the Queen.

Job functioned as bishop of Pécs from 1252 until c. 1282 and ispán of Moson County since 1272.

The clan divided into two branches: the first one had estates in Transdanubia, Tolna, Somogy and Baranya Counties.
