Here are all of the episodes. Link 2 is at the bottom of the page. Don't worry. I didn't see it at first either.
Its somewhat like Mission Hill. Unfortunately, like Mission Hill, it was only on for one season. Great show nonetheless.
And the main characters are as follows:-Abraham Lincoln-Ghandi-Joan of Ark-JFK-Cleopatra
And there are also many other great people who make little cameos throughout the show, for instance Elvis, Genghis Khan, and Van Gogh.
