The Parker sisters

In 1851, Elizabeth Parker, a free black child in Chester County, Pennsylvania, was bound and gagged, snatched from a local farm, and hurried off to a Baltimore slave pen. Two weeks later, her teenage sister, Rachel, was abducted from another Chester County farm. Because slave catchers could take fugitive slaves and free blacks across state lines to be sold, the border country of Pennsylvania/Maryland had become a dangerous place for most black people.
