I was wondering, with a blood test can't you track your family history. My great grandmother was pure indian but her birth certificate burned in a house fire. Can't I get a blood test to show I have indian in me? If so how much is it?

A DNA test can show many things, there are several good online companies that will send you a swab and you mail it in, and they will track your linage.

I am running late but do a Google search for online DNA test or something similar
