Baring-Gould’s sources: Irish Martyrologies. That of Tamlach, the Felire of -®ngus, the Cashel Kalendar, and the Martyrologies of Marianos Gorman and of Donegal Some Kalendars on March 16, others on Oct 27. No doubt one Abban was on the first day, the second on the latter; but which saint was commemorated on which day cannot now be decided.] There exists a Life of S. Abban, but it is full of chronological confusion, and spreads the events of his life over at least two centuries, so that it is probable that there were two Abbans abbots, one of Kill-Abban, the other of Old Ross and Maghamoidhe in Wexford. The first Abban is said to have been son of Lagnon, of the house of Dal Cormac in Leinster, and of Caoinech Abbadh, sister of S. Ibar, in which case he must have been bom about 430; according to other accounts his mother was Mella, sister of S. Coemgen, which would make his date 520, but the Abban of Magharof Abra and Azba, but they lived in the 5th century, and the Senkessar makes him bishop in the reign of El-Ezguagua, in the and century. S, Abban, noidhe, and not the Abban of Kill-Abban, was probably the son of Mella.

It is impossible to unravel the web of fable which passes as his Life, and to say what part of it belongs to which of the two saints of the same name.
