U.S. Rep. John Lewis will trace and discover his family’s ancestry on the season premiere of “Finding Your Roots With Henry Louis Gates Jr.” on March 25.

The show will air on PBS at 9 p.m.

Lewis, who has represented Georgia’s 5th District since 1987, will view the program with a small group of volunteers at the Park Tavern in Piedmont Park and hold a Facebook chat with Morehouse College students. He will meet and greet volunteers from 8 to 9 p.m.

Born into a sharecropping family outside of Troy, Ala., on Feb. 21, 1940, Lewis experienced the humiliation of segregation in education and public facilities and denial of the right to vote.

He committed at an early age to the goal of education for himself and justice for his people. Inspired by the example of Martin Luther King Jr. and Rosa Parks in the Montgomery bus boycott, he joined the struggle for civil rights. In the 1960s, he led the Student Nonviolent Coordinating Committee and was the youngest speaker at the 1963 March on Washington for Jobs and Freedom, where King delivered his famous “I Have a Dream” speech.

The new 10-part series, “Finding Your Roots,” taps into the basic drive to discover who we are and where we come from. It will air through May 20. It is the 12th series from Gates, who is an Alphonse Fletcher University Professor at Harvard University and director of the W.E.B. Du Bois Institute for African and African American Research.

Park Tavern is at 500 10th St. N.E. in Atlanta. For more information, visit www.pbs.org/wnet/finding-your-roots.
