One woman's unrelenting mission to reclaim her ancestors' history and honor their lineage pits her against one of the country's most powerful institutions: Harvard University Tamara Lanier grew up listening to her mother's stories about her ancestors. As Black Americans descended from enslaved people brought to America, they knew all too well how fragile the tapestry of a lineage could be. As her mother's health declined, she pushed her daughter to dig into those stories. "Tell them about Papa Renty," she would say. It was her mother's last wish. Thus begins one woman's remarkable commitment to document that story. Her discovery of a nineteenth-century daguerreotype at Harvard University's Peabody Museum of Archaeology and Ethnology, one of the first-ever photos of enslaved people from Africa, reveals a dark-skinned man with short-cropped silver hair and chiseled cheekbones. The information read "Renty, Congo." All at once, Lanier knew she was staring at the ancestor her mother told her so much about--Papa Renty. In a compelling account covering more than a decade of her own research, Lanier takes us on her quest to prove her genealogical bloodline to Papa Renty's that pits her in a legal battle against Harvard and its army of lawyers. The question is, who has claim to the stories, artifacts, and remnants of America's stained history--the institutions who acquired and housed them for generations, or the descendants who have survived? From These Roots is not only a historical record of one woman's lineage but a call to justice that fights for all those demanding to reclaim, honor, and lay to rest the remains of mishandled lives and memories.
