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.
