Ballwin is a city in western St. Louis County. Its population was 30,404 as of the 2010 census, and the city encompasses a total of almost nine square miles. Ballwin is unique in that it is the only city in the entire United States named Ballwin, unlike such cities of Baldwin, which are found in Kansas and Illinois.
The area was founded by a man named John Ball, whose father was a member of the Patriot Forces after he emigrated from Ireland to settle in Virginia in the mid-1700s. Records preserved in Jefferson City show a title transfer of 400 acres — along Grande Glaize Creek — to John Ball in February of 1800. This is the earliest official document of Ball’s settlement of the region, making up current day Ballwin.
In 1826, Jefferson City became the new home for Missouri’s capital and there was a need for a new overland mail route between the city of St. Louis and Jefferson City. The new route was established on a road that intersected Ball’s property. John Ball chose to make the most of the convenience it provided to his property, and laid out plans for a town.
Originally named Ballshow, the town was renamed Ballwin merely two days later and the name has been cemented ever since. The name is a hybrid of John’s last name and his belief of his town’s capability to “win” in both status and growth. Hence the “win” integrated into the name.
Residents of Ballwin are served by the Parkway and Rockwood School District.
