Ó Rodagh is an Irish surname meaning "descendant of Rodach". The personal name Rodach derives from the Irish element rod, signifying "spirited" or "furious." This patronymic surname reflects a common Gaelic naming tradition where the prefix Ó indicates "grandson" or "male descendant."Over time, the name has undergone Anglicization, with Ready appearing as a variant form. The Ó Rodagh name belongs to a broader class of Irish surnames formed from epithets describing temperament, such as Ó Maoilíosa (descendant of the devotee of Jesus) or Ó Conchobhair (descendant of Conchobar, meaning "lover of hounds"). Like many Irish surnames, Ó Rodagh has scattered bearers today, primarily in counties that experienced historical Gaelic influence.Meaning: Descendant of RodachOrigin: Irish/GaelicType: Patronymic surnameUsage regions: IrelandVariant: Ready
