The Story of Fynn

Fynn is an alternate spelling of Finn, derived from the Old Irish 'fionn' meaning 'fair,' 'white,' or 'bright.' The legendary Irish hero Fionn mac Cumhaill (Finn MacCool) gave this name its heroic resonance. In Irish mythology, Fionn was a warrior, hunter, and leader of the Fianna. The double-'nn' spelling Fynn gives a modern, distinctive twist to this ancient name.
