Hypermnestra (daughter of Thestius)

In Greek mythology, Hypermnestra (Ancient Greek: Ὑπερμνήστρα, romanized: Hypermnēstra, lit.'exceedingly memorable' or 'strong memory') was the daughter of King Thestius of Pleuron and Eurythemis, and the sister of Althaea, Leda, Iphiclus, Evippus, Plexippus, and Eurypylus.

Diodorus Siculus also mentions a figure named Hypmnestra, who he states is the daughter of Thespius, and the mother, by Oicles, of Amphiaraus (one of the Seven against Thebes), Polyboea, and Iphianeira.
