Ellyn is a spelling variant of Ellen, the medieval English form of Helen — from the Greek helios meaning sun or light. The Ellyn spelling, with the y, emerged as a fashionable American variant in the mid-to-late twentieth century. Ellyn peaked in 1991 alongside the broader American interest in vintage feminine names with the Ellen / Helen root, given a slightly distinctive American look through creative respelling.
