Book excerpt: Explores the family trees and genealogical identity of twelve remarkable Americans: Stephen Colbert, Louise Erdrich, Eva Longoria, Yo Yo Ma, and others. Since 2007, the Harvard scholar Henry Louis Gates, Jr., has been helping African Americans find long-buried details about their ancestors by researching their family trees and then, when the paper trail ends, by analyzing their DNA and marrying that information to a wealth of historical data. Now, in Faces of America, Gates explores the family trees of twelve of America’s most recognizable and extraordinary citizens, individuals who learn that they are of Asian, English, French, German, Irish, Italian, Jamaican, Jewish, Latino, Native American, Swiss, and Syrian ancestry: Inaugural poet Elizabeth Alexander, chef Mario Batali, comedian and television personality Stephen Colbert, writer Louise Erdrich, writer Malcolm Gladwell, actress Eva Longoria, cellist Yo Yo Ma, writer and director Mike Nichols, former monarch of Jordan Queen Noor, surgeon and author Dr. Mehmet Oz, actress Meryl Streep, and Olympic gold medalist and figure skater Kristi Yamaguchi. In addition, each of the subjects in Faces of America underwent dense genotyping to trace their genetic ancestry on their father’s line, their mother’s line, and their percentages of European, Asian, Native American, and African ancestry. Readers will share in the surprise and delight, the shock and sadness of these twelve individuals themselves as Gates unveils their rich family stories, traced back to their arrival on America’s shores, and beyond, deep into the history of their ancestors’ countries of origin. In this compelling book, Gates demonstrates that where we come from profoundly and fundamentally informs who we are today.
