 Historian Gyula Kristó said Ügyek's name may have been the chronicler' invention, since it derives from the ancient Hungarian "ügy" ("saint, holy") word.It is said, speculated or at least possible that the earlier Grand Princes of the Hungarians were also descendants of the Hun Khans, as well as other Turkic peoples, and through them from some daughters of Emperors of China.Simon of Kéza's "Gesta Hunnorum et Hungarorum" narrated that royal lineage that makes Hunnic ruler Attila the sixth-generation ancestor of Árpád, conqueror of the Pannonian Basin, through Attila's son Csaba, his son Ed, his son Ügyek, his son Előd, his son Álmos.
