How do you find out thier bloddlines

First and best resource would be her breeder. You can try searching for her parents using Yahoo or Google. AKC sells on line pedigrees for $10 (or maybe it is $8) which can sometimes be helpful. You can also search http://www.pedigreedatabase.com/gsd/search.html

Sometimes we can help too.

Nope nada Its ok I love her the same. I think shes alittle Larger then the normal gsd i think. 24.6 pounds at 11 weeks So most likely "american"

Weight can't tell you anything about lines ;-) Whopper puppies and small puppies come from all lines of GSDs

You can try posting the name of the pups parents and grandparents on here. I new a few breeders in the "region" if you want to PM me the name of the breeder I might (not definitely) be able to help there too.
