Nem Moccu Birn

Nem Moccu Birn (or Nennus, Nenus, Nehemias; died 14 June 654) was Abbot of Aran. His feast day is 14 June.

Biography
Nem was one of the few known successors of Enda of Aran, and appears to be the first such abbot listed in the Irish annals after Enda himself.

The word moccu is actually a contracted form of "mac Ua Birn", indicating that St. Nem was a descendant of Loegaire Birn Buadach, and early king of Ossory and thus a scion of the Dál Birn lineage of Ossory. In the Félire Óengusso, he is recorded as being a relation of St. Ciarán of Saigir.

Butler's account
The hagiographer Alban Butler (1710–1773) wrote in his Lives of the Fathers, Martyrs, and Other Principal Saints under June 14, "St. Nennus or Nehemias, Abbot Was of the family of the O'Birns. In 654 he succeeded St. Endeus upon his demise in the government of the great monastery of the isles of Arran, which formerly were two, before the name of Bute was given to one of them. The festival of St. Nennus has been always kept with great solemnity in many parts of Ireland. See Colgan in MSS. ad 14 Jun."
