Back to the other Titans I mentioned, Phoebe and Coeus. Phoebe (a moon goddess) and Coeus (god of ?) are the parents of Leto (Greek mythology)/ Latona (Roman mythology).
Anyway, to make this brief, Leto and Zeus (Gr.; Roman name is Jupiter, Latin name is Jove) had illegitimate twins. The twins are:
*         The God of Light- Apollo (both Greek and Roman name).
Apollo is also the patron god of medicine, music, inspiration, etc.

and

*         The goddess of the Moon- Artemis in Greek mythology; Diana in Roman mythology.
Artemis/Diana is also the goddess of the hunt, chaste love, maidens, and children.
