I like your name choices, but you would really have to talk me into
Eos. I would prefer her sister,
Iris. I do love Greek mythology names. I plan to use one for a girl if I have another daughter.
I wasn't liking the name
Berenice until I started reading the other people's comments. suddenly it reminded me of how I used to hate the name
Beatrice, until I studied
Dante's Inferno in college with an Italian professor.
He always pronounced it "bee-uh-TREE-chay" and after a while I started to think the name is incredibly beautiful. It's amazing what a difference the pronunciation can make on a name.
BTW, I went to school with a girl named
Io, also from a famous Greek myth. After getting familiar with the story, I really love the name because of what a strong character
Io had to be to endure what she did and still survive in the end.
