Abbanus ST., the name of two Irish abbots.
(1.) Of Cill-Abbain, in Ui-Muireadhaigh, County Meath, is probably identical with St. Abban of Cill-Abbain. He was originally named Blaih, and was a son of the sister of St. Ibar, the contemporary of St. Patrick, in the 5th century. Of him nothing certain is known. He is commemorated in the calendars March 16.
(2.) Of Magh-Arnuidhe, in Ui-Ceinseallaigh, County Wexford, the son of the sister of St. Coemgen, in the 6th century, is commemorated Oct. 27. Twenty monasteries are mentioned as having been founded by this saint, almost all in the southern half of Ireland. See O'Clery, Martyrol. Dungall.; Colgan, Acta SS. Hibernie; Acta SS.
