According to the Lebor Gabála Érenn (compiled in the 11th century), he was the leader of the third group of people to settle in Ireland: the Muintir Nemid (or Muintir Neimhidh, "people of Nemed"), Clann Nemid (Clann Neimhidh, "offspring of Nemed") or "Nemedians".
[4] According to the Lebor Gabála, Nemed, like those who settled Ireland before him, had a genealogy going back to the Biblical Noah.
[3] Also on board are his wife Macha, his four chieftain sons (Starn, Iarbonel, Annind, and Fergus 'Red-Side'), their wives and others.
[3] His wife Macha dies twelve days after they arrived and is buried at Ard Mhacha (Armagh).
Ráth Chindeich was dug in one day by Boc, Roboc, Ruibne, and Rotan, the four sons of Matan Munremar.
Modern scholars believe the Fomorians were a group of deities who represent the harmful or destructive powers of nature: personifications of chaos, darkness, death, blight, and drought.
[7][8] These battles are at Ros Fraechain (in which Fomorian kings Gann and Sengann[9] are killed), at Badbgna in Connacht, at Cnamros in Leinster (in which Artur, Nemed's first son born in Ireland, dies), and at Murbolg in Dál Riata (where his son Starn is killed by the Fomorian Conand).
This tribute may be "a dim memory of sacrifice offered at the beginning of winter, when the powers of darkness and blight are in the ascendant".
[3] Some of the survivors go "into the north of the world" and become the Tuatha Dé Danann, some go to Britain and become the ancestors of all Britons, and some go south to Greece and become the Fir Bolg.
This Nemed is described as a famous warrior king who raised two horses with the Fairy Folk of Síd Ercmon.
