Timandra was one of the daughters of King Tyndareus and Leda, daughter of King Thestius of Pleuron, Aetolia. Thus, she was the (half-)sister of the divine twins, Castor and Pollux, Helen, Clytemnestra, Phoebe and Philonoe. Timandra married Echemus, the king of Arcadia, and possibly with him had a son named Ladocus.
- "Steischorus says that while sacrificing to the gods Tyndareus forgot Aphrodite and that the goddess was angry and made his daughters twice and thrice wed and deserters of their husbands . . . And Hesiod also says:
- "And laughter-loving Aphrodite felt jealous when she looked on them and cast them into evil report. Then Timandra deserted Echemus and went and came to Phyleus, dear to the deathless gods; and even so Clytaemnestra deserted god-like Agamemnon and lay with Aegisthus and chose a worse mate; and even so Helen dishonoured the couch of golden-haired Menelaus."
