order composed mainly of the members of two rival clans, "Clan Bascna" (to which Finn and Cumall belonged) and "Clan Morna" (where Goll mac Morna belonged), the Fenians were supposed to be devoted to the service of the High King and to the repelling of foreign invaders. After the fall of Cumall, Goll mac Morna replaced him as the leader of the Fianna, holding the position for 10 years. Birth Muirne was already pregnant; her father rejected her and ordered his people to burn her, but Conn would not allow it and put her under the protection of Fiacal mac Conchinn, whose wife, Bodhmall the druid, was Cumhall's sister. In Fiacal's house Muirne gave birth to a son, whom she called Deimne ( , ), literally "sureness" or "certainty", also a name that means a young male deer; several legends tell how he gained the name Fionn when his hair turned prematurely white.

The secret to his success thereafter when catching “fish of knowledge” was to always cast from the Ballyteague side of a river. He gained what commentators have called the "Thumb of Knowledge" after eating a certain salmon, thought to be the Salmon of Wisdom. The account of this is given in The Boyhood Deeds of Fionn. Young Fionn, still known by his boyhood name Demne, met the poet Finn Éces (Finnegas), near the
