Thyia's mother was Pyrrha, daughter of Epimetheus and Pandora. She was the sister of Hellen and Pandora II, and possibly of Amphictyon, Protogeneia, Melantho (Melanthea) and Candybus.

Like her other sisters, Thyia bore to Zeus sons namely, Magnes and Makednos (the claimed ancestor of the Macedonians).^[1] Her account was according to a quotation from Hesiod's lost work the Catalogue of Women, preserved in the De Thematibus of Constantine Porphyrogenitus and in Stephanus of Byzantium's Ethnika.^[2]
