Ariel, I found this site about Greek Gods and Goddesses. You may be able to find some more ideas there. Best of luck writing your story.
TheDei Consentes
In Ancient Greek mythology, twelve gods and goddesses ruled the universe from atop Greece's Mount Olympus. Our main sources on the gods include Hesiod's Theogony and the Homeric Hymns (although they probably aren't by the Homer who wrote the Odyssey).
These Olympians had come to power after their leader, Zeus, overthrew his father,Kronos(or Cronus), leader of the Titans. All the Olympians are related to one another. The Romans adopted most of these Greek gods and goddesses, but with new names. There were many more deities in the Roman and Greek pantheons. We've included some of the more prominent deities below, in addition to the main Olympians. You can find a more complete list of Greco-Roman deities here.
Zeus (Roman name: Jupiter)
The most powerful of all, Zeus was god of the sky and the king of Olympus. His temper affected the weather, and he threw thunderbolts when he was unhappy. He was married to Hera but had many other lovers. His symbols include the oak and the thunderbolt.

Hera (Roman name: Juno)
Hera was goddess of marriage and the queen of Olympus. She was Zeus's wife and sister; many myths tell of how she sought revenge when Zeus betrayed her with his lovers. Her symbols include the peacock and the cow. ...
This isn't an official designation, but it's a handy catchall. These are the children of the Twelve Olympians, either by each other, by lesser deities, or by mortal women.
These include Pan (son of Hermes and a nymph), Asclepius (son of Apollo), Aeolus (son of Poseidon), Hebe (daughter of Zeus and Hera) and Heracles/Hercules (son of Zeus and a mortal woman). Fun fact, in Classical literature, the term demi-god was basically unknown. Instead hero and half-god were largely interchangeable. And, as in the case of Heracles, a hero could be elevated to full godhood.
The Titans
Greco-Roman mythology is replete with gods aside from the main bunch. The Romans had hundreds. There are lesser deities the Muses of Mount Parnassus, who inspire artists.
The most important are the Titans, who were the gods before the Olympians. The Titans are the children of Gaia, the earth, and Uranus, the sky. Like the Olympians, they consisted of a main twelve. They are Oceanus, Coeus, Crius, Cronus, Iapetus, and Hyperion, Theia, Rhea, Themis, Tethys, Mnemosyne, and Phoebe.
All of the main Olympians are the children and grandchildren of Cronus. The other Titans also had divine children, including the titans/gods Helios, Atlas, Amphitrite and Prometheus.
Many of the Titans were condemned to punishment in Tartarus, although some escaped this fate. Helios, for example, maintains a divine role in pulling the sun across the sky, and Amphitrite is the wife of Poseidon.
Other gods
Then there are the other types of gods. There are:
Primordial deities, who predate the Titans. These include Nyx, the personification of night, and the primordial Chaos.
There are the Chthonic deities who live underground beyond the River Styx. These include (sometimes) Hades/Pluto and Hecate, the goddess of witchcraft.
And there are personified concepts, such as Nemesis (vengeance), Eros/Cupid (lust), and Nike (victory).
