Ladislaus III
Julius I (often called as "the Elder" or "the Great" by contemporary documents in order to distuingish him from his namesake son) was the first known member of the "gens" (clan) Kán, which originated from Baranya County, but later acquired large-scale domains in Transylvania too. The later members of the clan were usually styled themselves as "Progenies Magni Jule Bani" ("descendants of Ban Julius the Great"). He married to the unknown surname Helena (died before 1250). They had two sons, by name Ladislaus I, who served as palatine (1242–1244/5), and Julius II, master of the cupbearers (1222–1228). His great-grandson was Ladislaus III Kán, an infamous oligarch, who ruled the province Transylvania "de facto" independently of the royal power for decades.
