Apollodoros, Bibliotheka 3.28-29
At the proper time Zeus loosened the stitches and gave birth to Dionysos, whom he entrusted to Hermes. Hermes took him to Ino and Athamas, and persuaded them to bring him up as a girl. Incensed, Hera inflicted madness on them, so that that Athamas stalked and slew his elder son Learchos on the conviction that he was a dear, while Ino threw Melikertes into a basin of boiling water, and then, carrying both the basin and the corpse of the boy, she jumped to the bottom of the sea. Now she is called Leukothea, and her son is Palaimon: these names they receive from those who sail, for they help sailors beset by storms. As for Zeus, he escaped Hera’s anger by changing Dionysos into a baby goat. Hermes took him to the Nymphai of Asian Nysa, whom Zeus in later times places among the stars and named the Hyades.

Photios, Lexicon s.v. Hyês
‘Rain-bringer’. An epithet of Dionysos, as Kleidemos says. Since we perform sacrifices to him during the time when the God makes it rain; but Pherekydes says that Semele is called ‘rain-bringer’ and that the children of Dionysos are the Hyades. Aristophanes lists Hyês among the foreign Gods.

Scholiast on Homer, Iliad 18.486
They say that the stars in the forehead of the constellation of Taurus are called the Hyades, but those on the half flank are called the Pleiades. For as Mousaios says, Atlas son of Iapetos and Aithra daughter of Okeanos had twelve daughters and a son, Hyas. A serpent killed him during a hunt in Libya, and five of the girls died while mourning their brother. The rest? Zeus placed among the stars and named the Hyades, taking their name from their brother. Most say the seven are slowly, † (text corrupt) the ones that died are called the Pleiades. And Pherekydes, as was noted previously, says that the Hyades are the Dodonian nymphs and Dionysos’s nurses, who entrusted Dionysos to Ino for fear of Hera, during which time Lykourgos also chased them … And Hellanikos in the first book of the Atlantidai says that the six joined with Gods, Taygete with Zeus, from whom was born Lakedaimon; Maia with Zeus, from whom was born Hermes; Elektra with Zeus, from whom was born Dardan; Alkyone with Poseidon, from whom was Hyrieus; Kelaino with Poseidon, from whom was Lykos; Sterope with Ares, from whom was Oinomaos; Merope with the mortal Sisyphos, from whom was Glaukos—for this reason she was faint.
