The story

How Sublette Township came to be

From Wikipedia’s history of Sublette Township.

Read it all →

The earliest references to Sublette as a town are from plat maps dating to the 1850s. At this point in time, Sublette was known as "Hanno" (named for Hanau, Prussia). It was a small cluster of houses just north of the settlement at Knox Grove.

In 1854, the Illinois Central Railroad built a line through Hanno and constructed a depot there for passenger and freight services. A plat map from the following year lists the town's name as being "Soublette" or the "Town of Soublett". The town name was officially changed to "Sublette" by an act of the state legislature in 1857. The name is unaffiliated with the town being sublet from the railroad; it likely traces back to an Americanized spelling of the French surname Soblet.
