Was the city of Atlanta named after a mythical character?

Answer 1

We have two conflicting accounts:

Wikipedia #1:

The U.S. city of Atlanta was named after Atalanta, via Martha Atalanta Lumpkin Compton, daughter of the governor of Georgia. The HMS Atalanta was also named for Atalanta.

Wikipedia #2:

Atlanta is derived from Atlas, a character in Greek mythology (and not the heroine Atalanta, as is often mistakenly assumed). Most cities or towns named 'Atlanta' are named after the Atlantic Ocean or some entity referencing the Atlantic Ocean, as in the case of Atlanta, Georgia, which was named for the Western and Atlantic Railroad, which in turn was named for the Atlantic Ocean.

So which is it?

Any budding historians or bloggers not afraid to call the state capital or county seat want to shed some light on this quandary?
