Electra, goddess of clouds and a sky nymph, married Thaumus, the minor god of the sea. She and Thuamus got married after a rain storm, when the sky touched with the mist, making a rainbow.  


Electra is the mother of Iris, Arke, Aello, Celaeno and Ocypete. She also gave birth to Iris' brother, Hydaspes. The river that they gave birth to Iris was named after Hydaspes.
