Did the greek goddess Athena have siblings?

Athena, the Greek Goddess of Wisdom, did not have siblings. She was the only child of Metis (Zeus's first wife) and Zeus. However, she did have lots of half-brothers and half-sisters, due to Zeus's many children. Some half-brothers and half-sisters include:

Ares, Hephaestus, Apollo, Hermes, Artemis, Dionysus, Hercules, Perseus, the Muses, and Helen.

Did that help? :)
