Hyginus listed Gaia, Thalassa and Ouranos as Hemera's children. While in Hesiod's "Theogony" Hemera was not mother of Gaia nor Ouranos, but mother of only Thalassa. Hemera got Thalassa with her brother Aether.
Hemera's mother was the goddess of the night and her father was the god of darkness. they were brother and sister and married and had kids Hemera was one of them. Her grandmother was the goddess of air. by:Lyndsy
