I like
Evie a lot. Unfortunately I don't love any full name quite enough to use myself and I'm also a little turned off by how popular
Evie has become. That being said, I really really like some full names for
Evie, especially
Eve,
Genevieve and
Evelyn.
I do love
Caoimhe enough to use and would use
Evie as an occasional nickname but I'm not sure I'd ever want to burden my kid with
Caoimhe outside of
Ireland and I don't like any of the Anglicized spellings.
