In Greek mythology, Queen Hypsipyle of Lemnos was the father of Euneus and ??? by Jason.

Aphrodite was angry at the women of Lemnos because they had forgotten to honor her appropriately; she cursed them with a horrific smell and the men of Lemnos abandoned their wives, taking Thracian concubines. The Lemnian women killed all their husbands and the new concubines, though Hypsipyle saved her father.

Later, the Argonauts stopped on Lemnos and had sex with the Lemnian women. Hypsipyle had two children with Jason, Euneus and ???.

When the other women learned that Hypsipyle had saved her father, they sold her into slavery.
