Clarus Mag Máilin

Clarus Mag Máilin (fl. 1215–51) Irish monk. Mag Máilin was a member of an erenagh and brehon family located in Moylurg, a kingdom in the north of what is now County Roscommon.

According to the Travelmania Ireland website,

• "Clarus Mac Mailin, son of the erenach of Inchmacnerin, who died 1251, founded the monastery of the Premonstratensians (reformed Augustinians), dedicated to the Holy Trinity, in 1215. The ranks of Canons were augmented in 1228 by the defection of monks from the Cistercian Abbey of Boyle, which was seen by the Cistercian Council of that year as having become too gaelicized. The monks brought with them their manuscripts and learning, which, under Clarus' direction, developed eventually into the great manuscripts of the Annals of Lough Key and the Annals of Connacht."
