Marion County

Marion County was formed from part of Ralls County in 1826. It was named for Francis Marion who was known as the Swamp Fox of the American Revolution. 

Marion County, organized December 23, 1826, is located in the northeast quarter of the state and is bordered on the east by the Mississippi River. The County seat of Marion County is Palmyra, Missouri. A court of Common Pleas was established in Hannibal, Missouri in 1844. As a result of the addition of the Court of Common Pleas, Marion County is unique from most third class counties in the state in that it has two courthouses.
