So the family likes Finnegan Leo. Is it too weird? How does it come off to you guys?
Thanks in advance...

Would you call him Finn for short? It sounds like a good name even though im not much of a fan of finnegan. Anytime i hear Finnegan i think of Casey and Finnegan from Mr. Dressup, a childrens TV show i grew up watching. Finnegan was a puppet of a dog if a remember correctly. But hey thats just my name assocation there, might not even be something you have ever heard of. Go with it if you love the name. I'd call him Finn as a nn though. Just cuter.

my son is named
Finnian "Finn" Pierce

even though Finnegan is nms, I think it goes well with Leo.
Finnegan Leo, the more I say it, the more likable it becomes.

ehh...its kinda crazy but i think finn could be a cute nm

Well, I really like Finn and Leo...not so much a fan of Finnegan, although I've heard FAR worse!! If the name's something you and the family likes, then I'd say go for it!
