“[2.21.9] The statue of the maiden beside the goddess (Leto) they call Chloris (Pale), saying that she was a daughter of Niobe, and that she was called Meliboea at the first. When the children of Amphion were destroyed by Apollo and Arternis, she alone of her sisters, along with Amyclas, escaped; their escape was due to their prayers to Leto. Meliboea was struck so pale by her fright, not only at the time but also for the rest of her life, that even her name was accordingly changed from Meliboea to Chloris.”
“[5.16.4] The (Heraean) games of the maidens too are traced back to ancient times; they say that, out of gratitude to Hera for her marriage with Pelops, Hippodameia assembled the Sixteen Women, and with them inaugurated the Heraea. They relate too that a victory was won by Chloris, the only surviving daughter of the house of Amphion, though with her they say survived one of her brothers. As to the children of Niobe, what I myself chanced to learn about them I have set forth in my account of Argos.”

Hippodamia founding the Heraean Games is one of my favorite games and considering that Hippodamia included Chloris (who was her niece) in the first games, it wouldn’t be too much of a stretch to say that perhaps Gorgophone (also her niece through Perseus who is her cousin) to be included in the games. I imagine Hippodamia’s children (Nicippe and Eurydice) were included as well.
