Round Prairie Township covers an area of and contains the unincorporated settlements of Carrington, near the headwaters of the Missouri River tributary Middle River, and Boydsville, near another MissouriRiver tributary bordering Boone County, although no incorporated settlements. It contains four cemeteries: Boydsville, Hundley, Millers Creek and Paris Fork; as well as the streams of Davis Creek, Millers Creek and Smith Creek also run through this township.
History
Created in May 14, 1821, the township initially covered at least the northern 2/3 of the western border areas of Callaway County, from 'the township line of 45 and 46 northward to the Audrain County line and eastward to a line along what is now the western boundary of West Fulton Township. If this description refers to boundary between Township 45 and 46, then it equates with a line near the southern city limits of New Bloomfield, explaining historical accounts of a historic Round Prairie Post Office later renamed New Bloomfield Post Office. In 1824, Round Prairie Township was reduced in size by the creation of Cedar Township to its south from what was the remainder of the western sector of Cote Sans Dessein Township, and within a year, in 1825, Round Prairie Township was further reduced substantially in size with the creation of a larger-than-today Bourbon township from its northern sector. This continued for about 60 years. A Round Prairie Post Office, from May 30, 1827 to June 16, 1841, 'about one-half mile north of New Bloomfield' was clearly inside Round Prairie Township boundaries of 1824, but near the boundary with the new Cedar Township created in 1825. The history of Round Prairie Post Office is complicated by the changes of township boundaries before and around the time of its opening; the reported move of New Bloomfield southward from its original site ; and the later creation of Guthrie Township from parts of Round Prairie and Cedar townships. Between 1883 and 1897, Round Prairie Township was again reduced in size by the creation of Guthrie Township from its southernmost area, at about the same time that Bourbon township was also reduced in size by the creation of Cleveland Township at the northwest corner of Callaway County). These changes are significant for research on historical events and genealogy.
