The Baby Name Wizard offers a comprehensive source for everything related to baby naming. You can simply search for names alphabetically, but I suggest digging deeper into the site; explore the NameVoyager, a colossal graphed database of the history and popularity of thousands of names (see screen shot below); check out the Namipedia, a name encyclopedia, and my favorite; the NameMapper, showing names’ popularity by state and year. Look at the lower screen shot for an example, using my favorite name for girls, Mia.
The Baby Name Wizard truly is a great resource to consult if you’re expecting a child. It sure makes things much easier and gives you one less thing to stress about.
