Mills published the first known set of district (county)
maps in an atlas of the state in 1825. Mills served as state
architect for South Carolina, designing the State Lunatic Asylum
and many local court houses, and later won the contest to design
the Washington Monument in Washington, DC. Mills
Atlas, made for the South Carolina State Legislature, contains
28 district maps and a state map, made from an earlier state
sponsored survey of all the districts from 1817 to 1821, signed
by twenty-two (22) different surveyors, and updated in 1825.
It was the first official atlas of the state of South Carolina.
After the U.S. Civil War, many counties created their own
maps showing railroads and key county roads. The first known
"road map" for the entire state was created in the
1910s, and with the establishment of the State Highway Commission
in 1917, their first "road map" was published by the
State in 1919. By the 1930s, the State Highway commission was
maintaining individual county road maps. This Author has only
been able to locate a few digital maps online, so far. As more
are found for Chester County, the Author will add them here.
