Actor Kelsey Grammer(Cheers, Frasier) traces his ancestry on his grandmother's side, uncovering the story of a woman haunted by demons and finding a connection to a family who risked everything in one of the greatest migrations in American history. Who doesn't love a good genealogy programme? Fine, nobody, but when you put a celebrity's ancestral history on display, you can guarantee we'll be watching, especially when it's Frasier Crane we're looking at.
