I really like
Cleo; it's unexpected but everyone knows how to say it and spell it (maybe you wouldn't get that so much with the variant
Clio, though).
I prefer it a million times over to
Chloe; which I really dislike due to how popular it was when I was growing up (had about five in my class I think and they were all vile!)
