Hermippe
In Greek mythology, Hermippe was a daughter of Boeotus. She was married to Orchomenus, son of Zeus and the Danaid Isonoe, but had a son Minyas with Poseidon. Orchomenus became legal father of her son.
The IAU Gazetteer of Planetary Nomenclature refers to Hermippe as "Consort of Zeus and mother of Orchomenos by him", apparently following an alternate version recorded by scholiasts on Homer.
