Don't forget to tune in! The Genealogy Roadshow: Historical Society of Pennsylvania episode premiers February 17 at 8 p.m. on PBS.

Genealogy Roadshow visits HSP during Season 2 and discovers fascinating Philadelphia family history. One woman’s ancestor may have sparked historic labor laws; a pastor may have an outlaw in her family tree; a woman learns about slave genealogy and – with the help of DNA testing – gets the answer she has waited for; and another woman learns her ancestor may have helped others escape the Holocaust.
