Cite needs to be fixed  Some info on Turners ancestry is cited to  httpwwwpbsorgpreviewsaalives   At least some of the info so cited appears not to be available at this link For example the results of a DNA test featured on African American Lives  showed Bullock aka Tina Turner was only  Native American  I havent been able to find that info on that website   I think that we should have a betterdifferent cite for this info or that we should cite this PBS program in a different format ie not by linking to its web page
