Erichthonius, Cacus, and Caeculus

No one was married to Athena, she was a "virgin" goddess. That did not mean gods and mortals did not lust after her, such as Hephaestus and the resulting son by way of his seed and Gaea, Erichthonius first king of Athens and her adopted son.

In Greek myth, her adopted son was Erichthonius (also written Erichthonios).
