If your families were in America prior to 1815, you may be curious about the overland routes over which they might have traveled. The road had to have at least a clearing through the trees and bridges or ferries for crossing streams. Map Guide to American Migration Routes, 1735-1815 by William Dollarhide, tells about and beautifully illustrates these early roads. Family historians can use them to trace the journey of ancestors.
