Iverni
The Iverni (Ἰούερνοι, Iouernoi) were a people of early Ireland first mentioned in Ptolemy's 2nd century Geography as living in the extreme south-west of the island. He also locates a "city" called Ivernis (Ἰουερνίς, Iouernis) in their territory, and observes that this settlement has the same name as the island as a whole, Ivernia (Ἰουερνία, Iouernia). These Iverni can be identified linguistically with the Érainn (Éraind, Érnai, Érna), a people attested in Munster and elsewhere in the early Middle Ages.
The prehistoric Érainn royal dynasties are sometimes referred to as the Dáirine.
