Their number, however, varies: Hesiod says they had ten sons and ten daughters, Herodotus that they had two sons and three daughters, and Homer that they had six sons and six daughters. Ovid and Apollodorus both mention seven sons and seven daughters.

Apollodorus2 mentions: Ismenus, Sipylus, Phaedimus (1), Tantalus, Agenor, Damasichthon, and Eupinytus. He lists the daughters as: Ethodaia (or Neaera), Cleodoxa, Astyoche, Phthia, Pelopia, Astycratia, and Ogygia.
Hyginus3 lists the Niobids as Tantalus, Ismenus, Eupinytus, Phaedimus, Sipylus, Damasichthon, Archenor; Neara, Phthia, Astycratia, Chloris, [corrupt], Eudoxa, Ogygia.
A famous statue is that of Niobe and her youngest daughter (Uffizi, Naples).
