DNA testing helps families verify biological kinships and reveals ancestral origins such as whether a person has Native American or Jewish heritage. Several tests are available. Presenter Kathleen Brandt will help you understand the test options and what to expect. She'll explore three case studies that used DNA to track down family history. Brandt has over 15 years of experience in international genealogical research and has appeared on "Who Do You Think You Are" on TLC and NBC, and "Finding Your Roots" on PBS and The History Channel.
