History
The land surrounding Barnhart originally belonged to Benjamin O'Fallon, who settled here with his family in 1834. The James O'Fallon Home was built in 1860, and was purchased in 1884 by Joseph G. Marriott, a cattle rancher who introducing the first Holstein cattle to Jefferson County. The extant home is now called the Parkton Mansion. The town was not named until after the Frisco Railroad was completed in the early 1900s, and may have been named for Mrs. C. L. Barnhart, who donated land for the Frisco Railroad Depot.
