Marion, Ohio, is a city located in Marion County, Ohio, and holds the county’s seat. The city is one of Ohio’s only cities founded by two people, in this case, Eber Baker and Alexander Holmes, which incorporated the city in 1821. It is named in honor of General Francis Marion, also known as the “Swamp Fox,” a military general who served in the American Revolutionary War. By 1840 the city had a total of 800 permanent residents, three churches, a private school, two newspaper offices, several general stores, and three mills, including a fulling mill, a sawmill, and a carding mill.

As time went on, the City of Marion continued to grow and prosper. In 2000, Marion had the largest population in Marion County, becoming home to over 38 thousand residents, over half of the total residents in all of Marion County. A lot of this growth came from the Delaware and Franklin county residents trying to escape the hustle and bustle of Columbus.

There are several museums throughout the City of Marion, including the Heritage Hall & Old Post Office, Wyandot Popcorn Museum, the Warren G. Harding House, the Huber Machinery Musem, and the Marion Union Station Museum. Marion is also home to the annual “Marion Popcorn Festival, The Marion County Fair, and Buckeye Chuck, ” Ohio’s official state groundhog that predicts the weather every year on February 2nd, also known as Groundhog Day.
