The town of Marshfield was platted on May 22, 1857, and named for Marshfield, Massachusetts, the home of statesman Daniel Webster.[2] A post office was established on April 6, 1857, which operated until 1989. In 1870, the population was 150 and, by 1900, it had grown to 250. In the late 1800s, the town had a dry goods store, a hotel, three churches, three saloons, two blacksmith shops, a grain warehouse, a wagon and carriage manufactory, a grocery store, a drug store and three physicians.[3]
In 2007, Marshfield consisted of a number of private residences, a grain elevator, a church and a body shop.
Marshfield is located in open farmland on County Road 450 South, about west of State Road 63, at an elevation of . Chesapeake Creek begins just east of town, and an early village named Chesapeake once stood about to the east. A Norfolk Southern Railway line runs along the east side of town, from Danville, Illinois, in the southwest to Lafayette in the northeast; the line carries about 45 freight trains per day.[4]
