Selected GIS Maps created by House Divided Project
The GIS map below created by Cooper H. Wingert helps visualize records from the Philadelphia Vigilance Committee and maintained by William Still documenting 995 freedom seekers during the 1850s. The radial lines illustrate the origins of the freedom seekers and their convergence at the Anti-Slavery Office at 31 N. Fifth Street in Philadelphia. Data compiled by William C. Kashatus and James A. McGowan. Originally published in William Still: The Underground Railroad and the Angel at Philadelphia (Notre Dame University Press, 2021), pp. 221-280.
