First things first, I'm so proud to be the first comment on the name Zadie; I'm surprised at the silence! Anyways, I love the way Zadie rolls off of the tongue; I think it has a cheerful, graceful sound to it. Zadie has everything that Sadie (also a beautiful name) has, except it doesn't look like "Sad and die" (which, lots of people said to ridicule the name Sadie). If "sad and die" in Sadie is a problem for you, why not consider the name Zadie? Zadie is one of my absolute favorite girl names!
