The Hag of Beara is said to have been born in Dingle, County Kerry, at Teach Mor or the Great House, described as the house farthest west in Ireland, and today identified as Tivore on the Dingle promontory. Along with County Kerry, she is also closely associated with County Cork, with the Book of Lecan (c.1400AD) detailing some of the stories around her legacy. In some tellings, she lived several lives, and is said to have been a mother or foster mother to the ancestors of a number of prominent clans, including the Corca Dhuibhne and Corca Loighdhe.
