I love the name
Finn! I prefer it on its own. Friends of mine have just had a
Finley and call him
Finn for short.
Finnegan is ok, but it's very much a surname to me. Or that song,
Michael Finnegan.
I'm neutral about
Finley /
Finlay for a girl. I met a girl Fin once. No idea if that was her full name or if it was short for something.
Finn over Fynn definitely!
