Help with girl names? What name would go well with this sibling set?

I want a name that would go with my other childrens names: Elizabeth (Bess), Joshua (Josh), Judith, Anthea, Naomi, Agatha (Aggie) and Thackery. I like quirky, old fashioned names. Our last name is Hightower. I honestly cannot come up with any names at all for this baby!! She totally has me stumped. If it were a boy, he would be Percy David. But I have no clue about what to name her. So help, serious help please lol, would be most welcome! Thanks!
