In the 1850s, Harriet Tubman rescued 70 enslaved people from Maryland's Eastern Shore and shepherded them north along the Underground Railroad. One of her regular stops was Auburn, New York, where she entrusted passengers to Martha Coffin Wright, a Quaker mother of seven, and Frances Seward, wife of William H. Seward, future secretary of state under Abraham Lincoln. They may not have looked it, but these women were dangerous and unconventional, and here Dorothy Wickenden reveals how they advanced the abolitionist cause as well as women's rights.
