St. Fintan of Clonenagh
A Leinster saint, b. about 524; d. 17 February, probably 594, or at least before 597. He studied under St. Columba of Terryglass, and in 550 settled in the solitude of the Slieve Bloom Mountains, near what is now Maryborough, Queen's County. His oratory soon attracted numerous disciples, for whom he wrote a rule, and his austerities and miracles recalled the apostolic ages. Among his pupils was the great St. Comgall of Bangor. When he attained his seventieth year he chose Fintan Maeldubh as his successor in the Abbey of Clonenagh. He has been compared by the Irish annalists to St. Benedict, and is styled "Father of the Irish Monks".
St. Fintan (Munnu) of Taghmon
Son of Tulchan, an Ulster saint, d. at Taghmon, 636. He founded his celebrated abbey at Taghmon (Teach Munnu) in what is now County Wexford, in 599. He is principally known as the defender of the Irish method of keeping Easter, and, in 630, he attended the Synod of Magh Lene, at which he dissented from the decision to adopt the Roman paschal method. Another synod was held somewhat later at Magh Ailbe, when St. Fintan again upheld his views in opposition to St. Laserian (Mo Laisre). But the views of the University Church prevailed. His feast is observed on 21 October. The beautiful stone cross of "St. Munn" still stands in the churchyard of the village.
