I'm just going to echo what was said previously.
Ellen and
Lynn are too close together; of the two,
Ellen is definitely the prettier name, I think.
Joanie as a given name is a nonstarter, but it's fine as a nickname for
Joan.
Joan and
Ellen and a third... hmm. I get a very 1950s-ish vibe here.
Meredith, maybe?
Louise?
Andrew
