Yup, yup. I don't mind Eleanor, but I'm firmly on Team Elinor. I agree that they feel totally different. Eleanor is somewhat cold and dour, while Elinor is so much warmer. It has a better personality.
Summer Rose is corny and really does sound like a Glade Plug-In. I just don't think Summer can be combined with a naturey name like Rose or Rain without sounding silly. While you're right that not everyone who meets her will know her full name, middle names do come up, and I would personally hate to give a child a combo she would have reason to feel embarrassed about.
