The area previously known as "McDaniel" was renamed "Lilburn", after the general superintendent of the railroad, Lilburn Trigg Myers of Virginia. (The basis of the name change got no official mention at the time, and historical researchers did not confirm the specific link to Myers until the 1990s.) The town prospered and was incorporated as Lilburn on July 27, 1910. A devastating fire and hard economic times in the 1920s ended the prosperity. A revitalization of the original historic area has emerged with shopping and restaurants in the Old Town district which has been described as a "slice of history."
