Titans

Phoebe is the Latin variation of the Greek name Phoibe, which derived from phoibos, meaning "bright." In classical mythology, Phoebe is the by-name of Artemis, goddess of the moon and of hunting. The masculine version of Phoebe is Phoebus.

Old-style creative name of the Greek mythological earth mother of all the gods. A lot better than the Roman equivalent: Ops. Rhea reentered the US Top 1000 in 2015. Its only previous appearance on the list since 1968 was 2004.

Theia is the Titan of sight and the shining light of the clear blue sky. She is the consort of Hyperion, and mother of Helios, Selene, and Eos. The name is more familiar in its Anglicized version, Thea.

Themis was the Titan -- one of the Elder Gods (or in this case Goddesses) -- of Justice and Order, usually depicted blindfolded and holding the scales of justice. Themis was the mother of the Fates and the seasons. While her name has fallen from mortal use, Themis might rise again along with such rediscovered goddess names as Aurora and Juno.
