Boxing legend Muhammad Ali was reportedly related to a slave who forewarned Union troops of a Confederate trap, according to the Washington Post.
Ali, born Cassius Clay Jr., is the great-great-great-grandson of Archer Alexander, whose likeness was used for the slave portrayed in the Emancipation Memorial statue in Lincoln Park near Washington, D.C.
