Butler’s Lives of the Saints – Saint Muredach, First Bishop of Killala, in Ireland


Saint Patrick, in his progress through Connaught, coming to a pleasant place where the river Moy empties itself into the ocean, built on the south banks a noble church called Kill-Aladh, of which he made Muredach, one of his disciples, bishop, about the year 440. It is situated in the county of Mayo. The bishops of this see have been sometimes called bishops of Tiramalgaid, now corrupted into the barony of Tirawly; sometimes of O’Fiacra-Mui, i.e., O’Fiacra, on the river Moy, a small territory; but since the twelfth century, of Killala, from Kill-Aladh. The festival of Saint Muredach is observed on the 12th of August. See Ware.
