Olympic Hestia

Here is the third one
Hestia, Goddess of household and the sacred fire.

Sister of Zeus, Poseidon, Hades, Hera and Demeter, Hestia was really calm and was the only one who never got involved in a fight. 
It is said that Hestia gave up her seat in favour of newcomer Dionysus to tend to the sacred fire on Mt. Olympus. Because of this, Hestia doesn't figure in many myths and she didn't roam or have any adventures.
Nevertheless, she was one of the Twelve Olympians who received the first offering at every sacrifice in the household.
Poseidon and Apollo aspired to court Hestia, but she kept virgin as her sisters Artemis and Athena.

Her equivalent in the Roman mythology is Vesta.
