Well, Nanas was a non-existent thing, but I managed to turn up a primordial Gorgon from the web called "Gorgon Aix" who in one case is the son of Typhon and Echidna.

"A few ancient sources also mention another Gorgon, one who predates the rise of the gods of Mount Olympus, this was the Gorgon Aix. The Gorgon Aix was a monstrous goat, with skin of serpents, who sided with the Titans early on in the Titanomachy. In these few sources, the Gorgon Aix is said to be the father of the other Gorgons with Ceto, although the monstrous goat is killed by Zeus during the war."

"Zeus defeated the gorgon Aex (or Aix), who was either the daughter of Helios (with a head as terrifying as her body was beautiful) or alternatively the son of Typhon and Echidna. He used the skin of a goat and fixed upon it the head of the gorgon Aex. It was said Zeus gave his Aegis to his daughter Athena once the war was over."

"Pseudo-Hyginus, Astronomica 2. 13 (trans. Grant) (Roman mythographer C2nd A.D.) :
"But when Jupiter [Zeus], confident in his youth, was preparing for war against the Titanes, oracular reply was given to him that if he wished to win, he should carry on the war protected with the skin of a goat, aigos, and the head of the Gorgon. The Greeks call this the aegis. When this was done, as we have shown above, Jupiter [Zeus], overcoming the Titanes, gained possession of the kingdom."

Pseudo-Hyginus, Preface (trans. Grant) (Roman mythographer C2nd A.D.) :
"From Gorgon and Ceto [were born]: Sthenno, Euryale, Medusa.

Pseudo-Hyginus, Fabulae 151 :
"From Typhon the giant and Echidna were born Gorgon . . . From Medusa, daughter of Gorgon, and Neptunus [Poseidon], were born Chrysaor and horse Pegasus."

Seems I have luck on my side after all, as Ceto was a female sea god and that Aix took the form of a goat - a symbol common for masculinity- with a coat of serpents, I now have some level of proof of a male Gorgon. Admittedly the tale diverges, this is just one version of it, but given thats the same for all mythological stories given enough time I'd say I have a reasonable foundation now. Regardless, in this tale they had Typhon as a grandpa, and given he was described "as a vast grisly monster with a hundred serpent heads "with dark flickering tongues" flashing fire from their eyes and a din of voices and a hundred serpents for legs" I figure he'd fit as backup.

Woo!
