Nem Moccu Birn
Irish saint

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.

Why this record matters
“Nem Moccu Birn” is worth following because a concise public description often conceals a longer documentary argument. Here, Moccu, Birn and Irish provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q4316832. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
