In the early 1900s, Arlington, which was then called "Lost Grove", was experiencing rapid growth and development. Many companies set up shop to profit from the people flocking to the jobs at the coal mines in this area of Illinois. The businesses included a mattress factory, beer brewery, numerous restaurants, a brothel, and many others. The mayor at the time was from New York, and changed the town's name to Arlington, after the town of Arlington, New York. Arlington was about the size of Peru, Illinois.
