Led by Baptist missionary William M. Pickett, this congregation was organized on Oct. 5, 1849, one year after the Mount Vernon Post Office was established. Early worship services were held in a log building located about one-half mile east of the Franklin County Courthouse. Originally known as New Liberty, the congregation adopted the name Mount Vernon Baptist Church in 1870. The church has had a number of outstanding members and pastors, including the Rev. Joshua F. Johnson, who later served as a member of the 1861 Secession Convention in Austin. (1984)
