Hello, Kay. Here's a tip on a migration map source that you may own already. In the back of Everton's _Handy book for genealogists,_ 8th edition, there are six maps of migration trails for the eastern U.S., midwestern, south central and southeastern states -- also "Canals and the Cumberland Road 1785-1850," and "Railroads by 1860." (I don't know if the same maps are in the recent 9th edition.) Cheers, Dolly in Maryland
