Why Ada?

• Parenting magazine says: ADA, ADAH. Ada pronounced "Ay-dah" is a Germanic name that was popular in the U.S. a century ago and still feels too great-grandmotherly to be ready for revival. Pronounced "Ah-Dah," it's a Nigerian Ibo name meaning "firstborn girl." Spelled Adah, it's a completely different Old Testament name, actually the first female name mentioned in Genesis after Eve. We think both "Ah-Dahs" feel more fresh and interesting than "Ay-dah."

Why Defne?

• Parenting magazine says: DAPHNE. When the writers of Frasier sought a recognizably English name for the character of Dad's companion, what they came up with was Daphne, which to many Americans does seem quintessentially British, and upper-class at that. Its roots are classical in Greek mythology, Daphne was a nymph who was saved from an over-amorous Apollo by having the gods transform her into a laurel tree. The place where this legend is said to take place has also been called as Daphne (now Harbiye), famous for its daphne trees and waterfalls, located 7km south of Antakya in Turkey.
