History from wikipedia:
Chautauqua County was
organized on June 1, 1875, by Richard
Stater; William Bowden; O. Hayson; H. S.
Alexander Sawver; George M. Ross;
John W. Morris; and John Sutter. These men
were all land promoters who soon left the
county after organization. It
contains the cities of Cedar Vale,
Chautauqua, Elgin, Niotaze, Peru and
Sedan, and was named
for Chautauqua County, New York.
The county seat dispute
between Sedan, which had been named by the
legislature as the county seat, and Elk
some officers remained with the
county records, continued for nearly two
years. Sedan offered to construct a
private funds if it was to be the
county seat. By 1877 the building was
completed and Sedan was the county seat.
