Great list! I really like Delia, Anna, Gwyneth, Ivy, and Lorelei. I do think you'll have pronunciation/spelling issues with Lorelei though. I like Calvin and Delia, Calvin and Anna, and Calvin and Ivy the best.
ETA - just saw your post that Anna is your DH's favorite. There must be something about that name...it's my DH's favorite too, and while I like it, I worry that it's too boring too.
