Nemedians

Nemed or Nimeth (modern spelling: Neimheadh) is a character in medieval Irish mythohistory. According to the Lebor Gabála Érenn (compiled in the 11th century), he is the leader of the third group of people to settle in Ireland, who are referred to as the Muintir Nemid (Muintir Neimhidh, "people of Nemed"), Clann Nemid (Clann Neimhidh, "offspring of Nemed") or Nemedians. The word nemed means "privileged" or "holy" in Old Irish. They arrive thirty years after their predecessors, the Muintir Partholóin, had died out. After many years the Nemedians too are wiped out or forced to abandon the island.

According to the Lebor Gabála, Nemed, like those who settled Ireland before him, had a genealogy going back to the biblical Noah. He was the son of Agnoman of Scythia, the son of Piamp, son of Tait, son of Sera, son of Sru, son of Esru, son of Friamaint, son of Fathochta, son of Magog, son of Japheth, one of the sons of Noah.

Ireland had been uninhabited since the Muintir Partholóin died of plague. The Muintir Nemid set sail from the Caspian Sea in 44 ships, but after a year and a half of sailing, the only ship to reach Ireland is Nemed's. Also on board are his wife Macha, his four chieftain sons (Starn, Iarbonel, Annind, and Fergus 'Red-Side'), and others. His wife Macha dies twelve days after they arrive and is buried at Ard Mhacha (Armagh). Two quite different dates are given for the arrival of Muintir Nemid: 2350 BCE according to the Annals of the Four Masters, or 1731 BCE in Seathrún Céitinn's chronology.

Four lakes burst from the ground in Nemed's time, including Loch Annind, which burst from the ground when Annind's grave was being dug. The other three lakes were Loch Cál in Uí Nialláin, Loch Munremair in Luigne, and Loch Dairbrech in Mide.
