The communities of Doyle and Livingston, combined in 1955 to create the Town of Livingston. Doyle was established northeast of present-day Livingston, located on Hog Branch, off present-day North Doyle Road but moved when the railroad was built from Baton Rouge to Hammond, and the community was re-located in 1901 by the McDonald family.
Livingston was started by the Lyons Lumber Company in 1916 as a logging community on 63 acres just west of Doyle, to support their logging industry and timber mill in Garyville, located south of Livingston on the Mississippi River. Therefore, Livingston and Garyville are sister cities.
When Livingston was first established there was a house on every lot, a board walk in front of every home, and water wells drilled on each corner so every home would have access to running water.
