Context paragraphs:
Paulding, Mississippi: Paulding is an unincorporated community in and one of the two county seats of Jasper County, Mississippi.  It is the only unincorporated county seat in Mississippi.  Settled in 1833, it was named by United States settlers in honor of Revolutionary War hero John Paulding.  After its citizens refused to contribute to a new railroad, the community was bypassed in favor of Bay Springs, Mississippi, which was designated a railroad stop to the west and the second county seat.  It attracted more development and industry.

Cottageville, West Virginia: Cottageville (also Moores Mill, Rhodess Mill, or Wrights Mill) is an unincorporated community in western Jackson County, West Virginia, United States.  It lies along West Virginia Route 331 northwest of the city of Ripley, the county seat of Jackson County.  Established in 1858, its elevation is 594 feet (181 m).  Although Cottageville is unincorporated, it has a post office, with the ZIP code of 25239.  It also is the site of the annual Jackson County Junior Fair.  Michael Coleman, a well known early Indian fighter, was killed and buried in the area, according to a historical marker placed by the state of WV.  The wooden Grist Mill located here since the 1840s burned to the ground in the summer of 1965.  Its foundation stones remain.  It had remained in operation full-time until 1930, part-time until 1937.  Cottageville was a commercial center with a bank, newspaper, tannery, blacksmith, several stores, a railroad station on the B & O and many other businesses in the early part of the twentieth century.  Its heyday faded with the closing of the mill and the improvement of roads in the county.  The B & O pulled up its tracks to the county seat, Ripley, in the mid-nineteen-sixties.  Less than a mile from the old town, the county operated what folks called the "poor farm," an early version of a welfare commune.  That closed in the thirties with the New Deal.  That land is now the Jackson County Junior Fairgrounds.

Coronado, Kansas: Coronado is an unincorporated community in Wichita County, Kansas, United States, was once a thriving community.  Platted in 1885, Coronado was involved in the bloodiest county seat fight in the history of the American West.  The shoot-out on February 27, 1887, with boosters—some would say hired gunmen—from nearby Leoti left several people dead and wounded.  Afterwards numerous famous lawmen from Dodge City, which included Wyatt Earp and Bat Masterson, gathered to calm the storm that ensued after the bloody fight.  A small town called Farmer City, which was located between Coronado and Leoti, was hoped by some to become the county seat—which would end the fighting.
