The name "Yaron" has two possible etymologies: a) it is a derivative of the Slavic disyllabic name "Yaroněgъ"; b) it is a phonetic adaptation of the calendar name of ancient Hebrew origin "Laron". In Rus', this name was never particularly popular. The first mention of the name dates back to 1219: Yaron — a boyar from Peremyshl, the thousandth of Mstislav Mstislavich. In 1685, the name appears in a record about the serf Yaron Mikula in the city of Uzhhorod.
