Very feminine names are needed?

We are pregnant with our first daughter! We don't want her having a boy or unisex name but we can't agree on any names! Right now our 'common ground' names are Scarlett, Charlotte, and Caroline. We like more traditional first names, our son's names are William Jonas (Will), Lucas Martin (Luke), and Jackson Paul (Jack). Please give us some other suggestions, her middle name will be Madeline!
