Philadelphia -- Franklin Institute

At Philadelphia's Franklin Institute, a team of genealogists uncovers fascinating family histories. A man learns that the event that drove his family to the City of Brotherly Love changed the course of history; a man may be a Viking descendant; another's family could have part of one of history's biggest scams; a young man hopes to confirm his relation to a signer of the Declaration of Independence; and two sisters learn their ancestors were part of the great Irish migration.
