Missouri Counties

Missouri has one hundred and fourteen counties and one independent city. St. Louis City is separate from St. Louis County and is referred to as a "city not within a county." Following the Louisiana Purchase and the admittance of Louisiana into the United States in 1812, five counties were formed out of the Missouri Territory at the first general assembly. Most subsequent counties were apportioned from these five original counties.

Maries County is a county located in the state of Missouri. Based on the 2010 census, the population was 9,176. Its county seat is Vienna. The county was organized March 2, 1855 and named for the Maries River and Little Maries River. 'Maries' is derived from the French marais, which means marsh, lake or pond.

Etymology - Origin of Maries County Name

Named for the Maries River. Maries is probably a corruption of the French "marias" meaning "marsh" or "swamp." The Maries River, like the upper reaches of the Osage River, was once said to be called Le Marias de Cygnes or "Marsh of Swans." It has also been suggested that the Big and Little Maries Rivers were named for two French girls and that the name is the plural of Marie.
