I think I'll add another:

Atlanta, I assume comes from the name of the Greek heroine, Atalanta. The resemblance in the two names is so similar that I'd be surprised it this isn't the origin. Atalanta was abandoned at birth by her father, who wanted a son, and she became one of the Argonauts. She was unwilling to be married but consented that she would marry anyone who could beat her in a foot race. (Apparently she was pretty fast.) Aphrodite, the goddess of love, gave one of the suitors golden apples to put in Atalanta's path. She could not resist the apples because they were magical, and bent down to pick them up, letting the suitor, her destined husband, pass her.

I don't know what this has to do with a city in Georgia, but I guess it's just an interesting name.
