What should I name my puppy?

I'm getting an Australian Shepherd in a week, and she'll be about 6 weeks old by then. I want to stick to a southern type name for her. I was thinking of names like Daisy, Maggie, Mandy, or Patsy (like Patsy Cline). my dad has a good friend who also has an australian shepherd and her name is Loretta, cause she came from Loretta Lynn's ranch. Anyways, give me opinions and ideas! Real answers please.
