Hesiod and Pseudo-Apollodorus place Mnemosyne among the Titan daughters of Uranus and Gaia. Her own name is Memory, and her children make remembrance audible: the Muses preserve the deeds of gods and mortals in song.2Hesiod · Pseudo-Apollodorus — Theogony 132–138; Bibliotheca 1.1.3⚖Told differently in other tellings — change the lens on the card

For nine nights wise Zeus entered her holy bed in Pieria, and when the seasons had turned she bore nine daughters of one mind, whose hearts were set on song. Hesiod calls them a forgetting of ills and a rest from sorrow; Pseudo-Apollodorus names them Calliope, Clio, Melpomene, Euterpe, Erato, Terpsichore, Urania, Thalia and Polymnia.3Hesiod · Pseudo-Apollodorus — Theogony 53–67, 915–917; Bibliotheca 1.3.1

Hyginus preserves an incompatible descent, making Mnemosyne a daughter of Jove and Clymene. Because that genealogy moves Memory two generations later than the Titan list, it is modeled as a disputed parentage rather than folded into the older account.4Hyginus — Fabulae Preface (Grant p. 30)⚖Told differently in other tellings — change the lens on the card
