If we consider the names of Hesiodic deities, we can note many similarities in
some names, implying a common origin. If they represent only one or many
sources, we can't know.
Okeanos and Ouranos seem to show the same suffix.
Kronos, Koios, Pontos, Kreios, Theia, Phoibe, Gaia, Maia show similar
formation: short nouns withou clear suffix, short vowels, thematic endings.
Zeus and Eos are IE.
Atlas, Thaumas, Pallas and Gigas show similarities to names like Mimas, Bias,
Korybas, Aias, Minyas, Phorbas.
Te:thus and Erinys: same suffix.
I'd guess that Styx, Thetis and Te:thys are different allophonous from the same
source, through dialectal or languague variation. Both Thetis and Styx were
sea-nymphs that aided Zeus in their war against his foes. Styx married Pallas,
begetting four allegorical entities; Thetis married Peleus and begot Achiles
Korybas (*korubant-) could be a doublet of Koures (*koure:t- < *korFa:t-), and
distantly related to Semitic root KRB (cf. karub, karibu, kerubim). Another
cognates or doublets could be Koro:nos, Kerberos, gryphos. Original meaning
could be something like "guardian animal deity".
Korybas/Koro:nos contrast sounds analogous to Phorbas/Phoro:neus
Mino:s (*minohu-) show striking similarity to Minyas (*minuFant-)
Male names with E:U-suffix and female names with O:(I)-suffix were numerous.
