Iverni
The Iverni (Ἰούερνοι, Iouernoi) were a people of early Ireland, first mentioned in Ptolemy's 2nd century Geography as living in the far south-west of the island. He also names 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).
