Recently, the National Park Service has been doing major study of the Underground Railroad in Pennsylvania.  The purpose of the NPS is to educate, serve, and get the community interested in natural and cultural resources throughout the country.  The National Park Services website lists six significant stops in Pennsylvania for fugitives along their path to freedom.
 

•     Oakdale - was the first stop north of the Delaware line on the Underground Railroad, often providing temporary shelter for fugitive southern slaves on their journey north.

•     White Horse Farm - In 1840, politician Elijah Pennypacker, opened his Philadelphia home as a major stop on the Underground Railroad.  Hundreds of fugitive slaves from three different routes, coming from neighboring counties and Delaware, were directed to the White Horse Farm.  Pennypacker personally transported slaves from his home to Norristown and other points to the north and east.  No slaves were ever apprehended while in his care.  Pennypacker now has a park in Philadelphia named after him.

•     Between 1770-1908, the Johnson House acted as the residence for five generations of the Johnson family.  The third generation was active in the Underground Railroad during eh 1850s.  The Johnson house and the Johnson's are among the leading abolitionists of their generation.

•     Built in 1812, the LeMoyne House was the center of anti-slavery activity in southwestern Pennsylvania from the 1830s throught the end of slavery.

•     John Brown House.  Brown lived here while he was developing his plan to attack Harper's Ferry in then Virginia and seize the Federal arsenal in 1859.  Due to his previous actions at 'Bleeding Kansas,' Brown went by the alias Dr. Isaac Smith while living at this Chambersburg house.
