Page "Fionn mac Cumhaill" Paragraph 4

Most of Fionn's early adventures are recounted in the narrative The Boyhood Deeds of Fionn.

He was the son of Cumhall – leader of the Fianna – and Muirne, daughter of the druid Tadg mac Nuadat who lived on the hill of Almu in County Kildare.

Cumhall abducted Muirne after her father refused him her hand, so Tadg appealed to the High King, Conn of the Hundred Battles, who outlawed him.

The Battle of Cnucha was fought between Conn and Cumhall, and Cumhall was killed by Goll mac Morna, who took over leadership of the Fianna.
