Map Guide to the U.S. Federal Censuses, 1790-1920; by William Dollarhide & William Thorndale; 445 pp; 8.5x11; first published in 1987, reprinted 2011; ISBN: 9780806311883; Item # GPC5786
The county has always been used as the basic Federal census unit. Genealogical research in the census, therefore, begins with identifying the correct county jurisdictions. This work (one of the top-five best selling genealogy books) shows all U.S. county boundaries from 1790 to 1920. On each of the nearly 400 maps the old county lines are superimposed over the modern ones to highlight the boundary changes at ten-year intervals. Also included are:
With each map there is data on boundary changes, notes about the census, and locality finding keys. There also are inset maps that clarify territorial lines, a state-by-state bibliography of sources, and an appendix outlining pitfalls in mapping county boundaries. The detail in this work is exhaustive and of such impeccable standards that there is little wonder why this award-winning publication is the number one tool in U.S. census research.
If you were to have only one American genealogy guidebook at your side, The Dollarhide Map Guide would be one to have.
