Family name origins & meanings

  • The McCoy clan of KY, led by Randolph McCoy, was involved in one of the bitterest mountain feuds, with the Hatfield clan of WV, from the Civil War to the end of the 19th century. The expression ‘the real McCoy’ probably originated with an American boxer, Norman Selby (1873–1940), who adopted the name “Kid McCoy” to distinguish himself from another fighter of the same name.
