Mirage - that's definitely a strong contender! I was also looking at some Native American names:
Chu'mana - Hopi - Snake Maiden
Chu'Si - Hopi - Snake Flower
Hehewuti - Hopi - Warrior Mother Spirit
Leotie - Flower of the Prarie (not sure which Nation)
Namid - Cheyenne - Star Dancer
Nuttah - Algonquin - My Heart
Adira - Noble, Powerful (not sure which Nation)
Lomasi - Pretty Flower (not sure which Nation)
And then there's Cheyenne or Dakota
