Oh and i forgot Loretta and Cora, if nobody's beat me to it. I don't how i could forgot those two beauties!
Lots of great suggestions already - I especially love Charlotte, Josephine & Annie :)
I just had to throw in one of my favorite Southern-inspired names that I don't think I saw listed yet: Magnolia! The tree is such a romantic southern image to me, and it lends itself to an adorable nickname, Maggie.
tfzolghadr's names feel spot-on.
Laurel and Lorna are so beautiful.
And I'm not sure about Tabitha and Frances; I might be the only one who hears those two as Southern.
