Kind: captions Language: en [Music] who isn't curious about family history where we came from who our people are we know nothing we have to rely on some of our older family members to really tell us what they remember I heard that they say he was a tall fast skinned man with green eyes and red hair my family is on a quest we're hoping that DNA testing can unlock secrets of the past because like so many families like ours family tree is incomplete before we started this ancestry research I didn't know anything about Lee hert Lee hert and Eliza Waller our oldest known patriarch and matriarch sit at the very top of our family tree they're kind of like our families Adam and [Applause] Eve Lee and Liza had 14 children and spawned a long line of descendants but other than that we don't really know that much about about them who are Lee and Liza and where did they come from I'm Byron hurt I'm a documentary filmmaker and I'm a member of the hurt Walla family I've always been super curious about our family's Origins Beyond Lee and Liza many European Americans are able to discover their family Roots using public records and genetic ancestry test kits but for African-American family amilies like mine the path to learning family history is much more challenging since emancipation black families torn apart during slavery have had to work hard to reunite and discover the truth about their past my family has no idea who Lee and Liza's ancestors are because unfortunately we can't go back any further than 1863 the year Lee hurt was born why is it so difficult for us as a family to learn the information that we need to learn about Lee her's parents his grandparents elza her's grandparents great grandparents and so on and so forth well our lives did not count in the way that other people's lives counted you know I mean if if we ever needed a black lives matter movement it would have been from our very Inception on these Shores Our Lives didn't count plus we don't have the scientific record of Africa that would allow us to make the the bridges that we know exist because we are an African people in North America the big DNA databases are mostly made up of samples from people of European descent with a lot fewer DNA samples from black people whether they are now living in Africa or the Americas the African database is not robust there's not a lot of information within the database because the way that that genetic sequencing and ancestry reconstruction works is that you take an unknown sample say your sample and then we try to match it to samples that we have already identified if we can't match the unknown sample to samples that we have already identified then we have a problem DNA can tell you some of your family history but it's not all encompassing
