The name Tyrone is believed to derive from the Greek “Turannos” meaning “sovereign” or “king.” Additionally, Tryone is a location name in Ulster county in northern Ireland, which is believed to derive from the Irish Gaelic “Tir Eoghain”meaning “land of Eoghan” or “land of the noble.” “Owen” is an anglicized form of “Eoghan,” so it also means “land of Owen.”
