The name Helen is a Greek baby name. In Greek the meaning of the name Helen is: Shining light. The bright one. Helen of Troy, whose elopement with Paris sparked the Trojan War, was the daughter of Zeus and wife of Menelaus, King of Sparta.
Ellen itself is the Medieval form of Helen, from the Greek Helene, which could be derived from Selene, from the Proto Indo-European light, brightness. It can be argued that this is a second meaning of the name Eileen.
