Finding Your Roots (8 p.m., UNC-TV) – Readers of this blog know that this is one of my favorite shows. It consistently has great guests with fascinating genealogy stories. This week’s episode – it’s Greek Week! – may just do me in. Henry Louis Gates Jr. explores the family trees of Tina Fey, George Stephanopoulos and Raleigh’s own David Sedaris. If there are two things I love, it’s a genealogy show and a Sedaris! Among the big revelations are that Sedaris’ great-grand-aunt was taken captive by the Ottoman military and that one of Fey’s ancestors was a hero in the Greek War of Independence.
