Kállay family is a Hungarian noble family. The family name derived from their estates at Nagy-Kalló, in Szabolcs, and they claimed descent from the Hungarian Balogh-Semjén genus (clan), which colonized the counties of Borsod, Szabolcs, and Szatmár, at the close of the 9th century. János Kállay de Nagy-Kálló was given the title Count by Hungarian Queen Maria Theresia in 1778, but the comital line became extinct. Hungary's 2014 Eurovision Song Contest representative András Kállay-Saunders is a descendent of the Kállay family. He came 5th in the contest.
