History

Audrain county was formed from a non-county area with portions under the administration of Montgomery, Callaway, Boone, Ralls, or Monroe counties at various times prior to its official establishment in 1836. Thus, records for locations now in Audrain prior to 1836 may indicate location in those counties instead. Some details have been summarized on the website of the Northeast Missouri Genealogy Village, and a dynamic map showing some of the changes is on the ‘mapgeeks’ website showing historical maps of the states of the United States. (See ‘External Links’ below.)

Today’s Audrain County historical website data (see ‘External Links’ below) indicates that the county was divided about 50/50 during the historic US Civil War and that US Army Commander General Ulysses Grant was resident there briefly during that time. While Audrain county shared some history with neighboring counties, it does not border the Missouri River.

According to some Confederate historian publications, Audrain County was one of several nearby counties settled by migrants from the Upper South, especially Kentucky and Tennessee; that some brought slaves and slaveholding traditions with them, cultivating crops similar to those in Middle Tennessee and Kentucky such as hemp and tobacco, or brought antebellum architecture and culture; and that the county was considered by those historians to be in the heart of what was called “Little Dixie”.
