The Pennsylvania Historical Society has the John Rodgers Family Papers
which includes, "the 1830 agreement between Rodgers and Jacob Swimley regarding the building of a house in Washington, D.C." I wonder if that may have a floor plan? Someone more experienced with real research check out "Box 1: 17"
Has anyone contacted the Historical Society of Pennsylvania regarding the agreement between Rodgers and Swimley? There is a Research by Mail service available.This service is especially useful to those who cannot visit the library in person. For a pre-paid fee, a skilled staff researcher will investigate and respond to your research request utilizing sources available in our library and manuscripts collections. Please see our Research by Mail section or call 215-732-6200 ext. 209 for further details.
