The 10-part series “Finding Your Roots” that is airing on GPB through May 20 will offer family historians tips on family searches and insights into celebrity genealogy.

Cultural critic and Harvard scholar Henry Louis Gates Jr. hosts the series, which airs at 8 p.m. on Sundays.

The series journeys deep into the ancestry of a group of remarkable individuals and provides new understanding of personal identity and American history.

Among those featured are Samuel L. Jackson, John Legend, John Lewis, Branford Marsalis, Kevin Bacon, Cory Booker, Angela Buchdal, Geoffrey Canada, Margaret Cho, Harry Connick Jr., Robert Downey Jr., Dr. Sanjay Gupta, Yasir Qadhi, Condoleezza Rice, Michelle Rodriguez, Kyra Sedgwick, Wanda Sykes, Ruth Simmons, Martha Stewart, Barbara Walters and Rick Warren.

“Finding Your Roots” builds on the success of “African American Lives,” “African American Lives 2” and “Faces of America.” It is the 12th series from Gates, who is the Alphonse Fletcher University Professor at Harvard University and director of the W.E.B. Du Bois Institute for African and African American Research.

Gates finds new ways to “get into the DNA of American culture.” In each one-hour episode, he takes viewers along for the journey with one celebrity pair bound together by an intimate, sometimes hidden link; treks through layers of ancestral history; uncovers secrets and surprises of their family trees; and shares life-altering discoveries.
