I don't think Hebe is Greek, and I looked at every greek mythology book in my school library.
According to the Wikipedia,
SupernaturalJem is right! In Greek mythology, Hebe was the goddess of youth. The name Hebe comes from the Greek word meaning "youth" or "prime of life". Hebe was the cupbearer for the gods and goddesses of Mount Olympus, serving their nectar and ambrosia, until she married Herakles (Roman equivalent: Hercules).
