After ignoring it for most of my life, I'm starting to really like it. Ellen is pretty in a quiet way, softer than Helen, sturdier than Elinor...it's very appealing. I'd like very much to see it revived.
Ellen is like Susan, Patricia, Deborah, and other mid-century names. I only ever run into it on women who are decades older than I am and, on them, it feels boring and easy to ignore. Meeting a little 21st-century girl named Ellen, on the other hand, would delight me. I think, on her, it would feel fresh and unpretentious.
