Tiernan— “Kelt, kingly”
Tighearnach was an Irish saint, who flourished at the end of the fifth century, and whose dish is still preserved at Rappa Castle, in Tirawley, by the name of Mior Tigearnan, or the dish of St. Tiernan. Tigearnach became common among Irish princes, and even appears in English history, when Tigearnach O'Rourke was robbed of his wife. It was long in dying out among the Erse population, and remains as a surname in the form of Tiernay.
