Book excerpt: Using the unique approach that he has employed in his previous books, author, columnist, and television commentator James Burke shows us our connections to the fifty-six men who signed the Declaration of Independence. Over the two hundred-plus years that separate us, these connections are often surprising and always fascinating. Burke turns the signers from historical icons into flesh-and-blood people: Some were shady financial manipulators, most were masterful political operators, a few were good human beings, and some were great men. The network that links them to us is also peopled by all sorts, from spies and assassins to lovers and adulterers, inventors and artists. The ties may be more direct for some of us than others, but we are all linked in some way to these founders of our nation. If you enjoyed Martin Sheen as the president on television's The West Wing, then you're connected to founder Josiah Bartlett. The connection from signer Bartlett to Sheen includes John Paul Jones; Judge William Cooper, father of James Fenimore; Sir Thomas Brisbane, governor of New South Wales; an incestuous astronomer; an itinerant math teacher; early inventors of television; and pioneering TV personality Bishop Fulton J. Sheen, the inspiration for Ramon Estevez's screen name, Martin Sheen.
