Monrovia, also known as Vaughn Corners or Thompson Mill, is an unincorporated community in Madison County, Alabama, United States. It is bordered on the south by the city of Madison, on the southeast by the city of Huntsville, on the west by Limestone County and on the north by the community of Harvest.
A post office operated under the name Monrovia from 1878 to 1904.[1]
Jeff Gin, located on the southwest corner of the intersection of Jeff Road and Nick Davis Road, began operation in 1956. It was started by brothers Erle and Wilburn Douglass. At that time the gin was called Douglass Brothers and was one of 26 gins in Madison County. Along with the gin, Erle had a farming operation with Jack Vandiver called Douglass & Vandiver. Jack Vandiver ended up managing the gin. By 1972, Wilburn Douglass and Jack Vandiver realized they did not have enough time to farm and run a gin, so a decision was made to make the gin a co-op, and the name was changed to Jeff Gin Company.[2]
