The town of Hartford was first called Gwynn when it was originally settled. Prior to 1900, the town saw the arrival of the Rock Island Railroad, and the town's name was changed to Hartford. Hartford was incorporated in 1900 and as a result, the old original town of Hartford, about one and a half miles west and named for a creek crossing belonging to the Hart family, is now generally referred to as "Old Town" or "West Hartford". According to Goodspeed's "History of Arkansas", William J. Fleming and William Stevenson opened the first store in West Hartford. By 1891 there were several businesses, a public school, and a Union Church edifice used respectively by Methodists, Baptists, and Cumberland Presbyterians.
