Caoilfhionn was the first name I encountered that made me love Irish names. I don't remember how I came across it, but I was like 12-13 and thought any language that can put that many seemingly unnecessary letters into a name that simple is awesome. :)
I also love
Eanna, and am not sure how I never came across
Enda since it's in the database! Maybe it's a fairly recent addition. I think
Joanie likes
Eanna, too, but other than us it never has got great reviews around here.
