Felim

Felim was an Irish priest and hermit, born, as is believed, in the region of Meath in the middle of the sixth century. Through his father, Carill, he descended from the line of Niall of the Nine Hostages. A well-⁠attested tradition shows him as a monk at the monastery of Slanore, near Crossdoney.

He later lived as a hermit near Kilmore in County Cavan, where he founded a monastery called Cill Mór, the Big Church. He is regarded as the first known bishop of Kilmore and the patron of the diocese of Kilmore. According to local tradition, the cathedral at Kilmore stands on the site of his first church. He is a saint of the undivided Church, venerated in the West.

The Martyrologies of Tallaght and Donegal give 3 August, the day on which the saint's annual fair at Kilmore began; the other calendars have 9 August.

His commemoration falls on 9 August (new calendar); the Churches on the Old Calendar keep the same day of the Menaion on 22 August of the civil calendar.
