Here are slides from a presentation to CAIS colleagues to help PBL learners get started with research about the Underground RR history in their community.
Fugitive slaves entered Connecticut at a number of points. Some passed through the state by way of Stamford, New Haven or Old Lyme, often traveling on to Farmington, the “Grand Central Station” in Connecticut.

Development of the Wellman Scale
To provide a clearer picture of what the Underground Railroad looked like in its time and to aid researchers in evaluating particular sites today, Judith Wellman, Professor Emerita of History at the State University of New York and President of Historical New York Research Associates, developed a five-point scale for evaluating and rating the likelihood that a claimed site was actually involved in the Underground Railroad. Her work in developing what has come to be known as the Wellman Scale was supported by grants from the National Park Service and the Preservation League of New York State. http://urrfreepress.com/#Scale
