Finn

Finn is an Old Norse and Old Irish name with dual origins: in the Norse tradition it derives from Finnr, meaning "a Finn" or "a person from Finland," while in the Irish tradition it comes from the Old Irish fionn, meaning "fair" or "bright." The most celebrated bearer is Fionn mac Cumhaill, the legendary Irish hero and leader of the warrior band known as the Fianna, whose tales form a central pillar of Gaelic mythology. The name has enjoyed widespread modern popularity across English-speaking countries and Scandinavia. Related forms include Fionn, Fingal, and the feminine variant Finna.
