The Irish surname Dougherty is of patronymic origin. The Dougherty's are named after Dochartach, the 12th in linear descent from Conall Gulban (d. AD 455), the son of the famous Niall of the Nine Hostages (Niall Noigíallach) a 5th Century High King of Ireland, and namesake of the powerful Uí Néill dynasty. Through Niall, the Dougherty's can trace their heritage back even further, making the clan one of Europe’s longest descent lines. The name is primarily found in county Donegal.
