Ellen

Ellen is an English and northern European form of Helen, itself derived from the ancient Greek name Helene, whose root is most likely related to the Greek word helene, meaning torch or corposant, though some scholars connect it to selene, meaning moon. The name was borne in legend by Helen of Troy and in Christian tradition by Saint Helena, mother of the Roman emperor Constantine, whose veneration helped spread the name throughout Europe. Ellen emerged as a distinctly common form in medieval England and Scandinavia, and remains widely used across the Germanic and Nordic languages. Related forms include Helena, Eleanor, Elaine, and Elin.
