Larne in Antrim; Latharna (Laharna: Book of Leinster), the district of Lathair [Laher], son of Hugony the great, monarch of Ireland before the Christian era. Until recently it was the name of a district which extended northwards towards Glenarm; and the town was then called Inver-an-Laharna, the river mouth of (the territory of) Larne, from its situation at the mouth of the Ollarbha or Larne Water.
