Appleton's Cyclopedia of American Biography, published in New York from 1887 to 1889, contained biographical information about thousands of people (some famous, some more obscure) in American history.
"But thirty years after the Cyclopedia's initial publication, questions began to be raised about its reliability. . . . To date over 200 suspicious entries have been flagged. But due to the enormity of the work it's doubtful that all of the false information it contains will ever be identified" (Museumofhoaxes.com, accessed 11-21-2008).
