Electra

Latinized form of Greek Ἠλέκτρα (Elektra), derived from ἤλεκτρον (elektron) meaning "amber". In Greek myth she was the daughter of Agamemnon and Clytemnestra and the sister of Orestes. She helped her brother kill their mother and her lover Aegisthus in vengeance for Agamemnon's murder. Also in Greek mythology, this name was borne by one of the Pleiades, who were the daughters of Atlas and Pleione.
