Helios is the brother of only Selene.
 Nonnus has Selene and Endymion as the parents of the beautiful Narcissus, although in other accounts, including Ovid's Metamorphoses, Narcissus was the son of Cephissus and Liriope
 In the Odyssey, Theogony and the Homeric Hymn to Demeter, Helios is once in each work called  (Hyperionds, "the son of Hyperion") and this example is followed by many later poets (like Pindar), who distinguish between Helios and Hyperion; in later literature the two gods are distinctly father and son
