Atalanta

Her name means equal in weight, in that she could hunt as well as (or better than) a man, but I think it is significant that it also refers to her appearance. Ovid says you would call her features girlish in a boy, or boyish in a girl, then later "such beauty as... Adonis, if (he) were a woman." As such I think this seems a great name for someone declaring themselves non-gender specific.

The meaning is great with a little context. What they've written here about the hero Atalanta is far from the full story. That's right, I said hero. She was pretty much the only woman in Greek myth to receive treatment similar to that of a male hero. She was rejected by her father who wanted a son and left to die, suckled by a bear and raised by hunters, single-handedly killed two aggressive and powerful centaurs when they tried to rape her, was the first amongst a group of hunters (comprised of heroes like Jason and Theseus) to manage to wound the Calydonian Boar, and according to some sources was one of the Argonauts. Oh and she beat Peleus, the father of Achilles, in a wrestling match - who was one of the most skilled wrestlers in all of Greece. In this context her name implies that she is equal to a man in power, strength and heroism.
