Hestia is the name of the Greek goddess of the hearth, home and chastity. Though Hestia has been long dormant as a name, it's a possibility for the parent in search of a classic name with deep roots that's also unusual.
Hestia is one of the least known Olympian gods of Greek Mythology. She is the goddess of Home and Hearth (fire) and is the sister of Zeus, Poseidon, Hades, Hera, and Demeter. She gave her Olympian throne to Dionysus.
