Re: Daphne, Danielle, Delilah
1. Daphne - It's heard of but not used often; a little Daphne these days would likely be the only one in her class/school.
2. Danielle - A bit boring, but I wouldn't be at all opposed to using Danielle if I *had* to.
3. Delilah - The biblical namesake isn't the best association, and I also think of the radio personality (not really either a good or bad association). The name is a little too frilly, like something a celebrity might use. I really like plain old Lila though!
So, Daphne.
