What does the name Fynn mean?
Fynn is a spelling of Finn, pronounced the same way, so it shares Finn's meaning and origin.
Finn has two main sources. In Irish it is an old form of Fionn, from a word meaning 'white, fair, bright', the name of the legendary hunter-warrior Fionn mac Cumhaill (Finn McCool). In Scandinavian use Finn comes from Old Norse Finnr, 'a Finn' or 'a Sámi person'. DMNES gives both derivations, and Wikipedia agrees. Fionn is the modern Irish spelling.
finn (Old Irish, “white, fair, bright”)Finnr (Old Norse, “a Finn, a Sámi”)
How sure is this? Uncertain. Two independent origins (Irish and Norse); DMNES gives both.
