Fir Domnann

The Fir Domnann were an ancient Irish people located in the west and north of Connacht, in Irrus Domnann, from which Erris in County Mayo now takes it's name. In Irish mythology they make up one third of the Fir Bolg. According to O'Rahilly's historical model they were related to the British Dumnonii, and to the Irish Laigin. They also provided the placename Inber Domnann, an old name for the Broadwater Estuary-Malahide Bay inlet in north County Dublin.

In the TĂĄin BĂł CĂșailnge, Ferdiad, the best friend and foster-brother of CĂșchulainn, by whom he was killed, was of the Fir Domnann.
