Kaplon (chieftain)
Kaplon was a Hungarian tribal chieftain, the second son of Kond, who was one of the seven chieftains of the Magyars according to Anonymus, author of the Gesta Hungarorum. It is possible that Kurszán, who was killed in 904, was his elder brother.
After the Hungarian conquest of the Carpathian Basin, the brothers Kücsid and Kaplon settled in the Nyírség, northeastern part of the Great Hungarian Plain and founded a monastery in Kaplony, near the Ecsed Marsh. Chieftain Kaplon was the ancestor of the gens Kaplon. The Károlyi, Bagossy, Csomaközy, Vadai and Vetési families were also originate from that genus.
