< Euphemus, son of Theiodamas >
1 Origin
Euphemus was born in Dryopis in 1270 BC
2 Family
Euphemus married Laonome, daughter of Amphitryon. [Tzetze.2.610, TzeAdLyco.886]
Laonome was the sister of Heracles, and Euphemus and Heracles were stepbrothers.
Euphemus married Lamache, who lived in Lemnos. [TzeAdLyco.886]
Euphemus and Lamache had a daughter, Leukophanes. [TzeAdLyco.886]

3.1 False traditions
Apollonius, Hyginus, and Pindar report that the mother of Euphemus, who appears in the story of the Argonauts' expedition, was Europa, the daughter of Tityus. [Apollo.1.179, Hyginus.14, Pind.Py.4.45]
However, if I create a genealogy, Europa's son Euphemus was born after the Argonauts' expedition in 1248 BC.
It seems more likely that the mother of Euphemus, one of the Argonauts, was Mecionica, the daughter of Orion, rather than Europa. [Tzetzes.2.610, Hesiod.GE.F6]
3.2 Father of Euphemus
Hyginus reports that Hylas was the son of Menodice, the daughter of Orion, and Theodamas. [Hyginus.14]
Hylas, son of Theiodamas (or Thiodamas), was also one of the Argonauts. [Apo.1.9.19, Apollo.1. 1344, Hyginus.14]
So Euphemus was the son of Theodamas and Menodice, daughter of Orion, and the brother of Hylas.
3.3 Emigration to Lemnos
Euphemus migrated from Dryopis to Lemnos.
The reason for the migration was a battle between Phylas, king of Dryopes, and Heracles. [Diod.4.37.1]
Dryopes, who lost the battle against Heracles, migrated to Euboea and Argolis. [Diod.4.37.2]
It is assumed that Euphemus, who was married to Laonome, sister of Heracles, also migrated at this time.
3.4 Wife of Euphemus
Euphemus migrated to Lemnos and married Lamache. [TzeAdLyco.886]
Lamache is assumed to have been one of the Minyans who migrated from Iolcus in Thessaly to Lemnos in 1236 BC. Herodotus describes the descendants of Euphemus as Minyans. [Herod.4.150]
Euphemus' ancestor was Dryopes, and through his marriage to Lamache, Euphemus probably became one of the leaders of the Minyans who lived in Lemnos.
3.5 Descendants of Euphemus
The fourth generation of descendants of Euphemus emigrated to Thera. [Pind.Py.4.45]
In 630 BC, Battus, son of Polymnestus, a descendant of Euphemus, led a colony from Thera to Libya and founded Cyrene. [Herod.4.150-158]
Battus was the seventeenth generation of descendants of Euphemus. [Pind.Py.4.5, TzeAdLyco.886]
