Somonauk is a small village located in Illinois, a state in the United States. It sits across two counties: DeKalb and LaSalle. In 2020, about 1,786 people lived there.

Most of Somonauk, the part in DeKalb County, is considered part of the larger Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area. This means it's connected to the big city area around Chicago. The smaller part in LaSalle County is near Ottawa.

Early History of Somonauk

The name "Somonauk" comes from the Potawatomi Native American people. It likely means "pawpaw grove." Pawpaws are a type of fruit tree that grew a lot in this area long ago.

Treaties and Early Settlements

In 1829, a treaty was signed that set aside land for Chief Awn-kote and his Potawatomi group. This land was near the Fox and Illinois Rivers. The Potawatomi, along with other tribes, helped the U.S. in the Black Hawk War. After the war, they were allowed to hunt on U.S. land.

However, white settlers became worried about the Potawatomi. By the end of 1833, the Potawatomi had left Illinois. This opened up the land for new settlers.

Moving the Village Name

In 1834, the first white settler arrived in DeKalb County. They set up a cabin near the Fox River. This cabin became a stop for mail carriers on the route between Chicago and Galena. This area was first called "Somonauk." It's known today as "Franks."

This cabin also became the first post office in the area. About 30 settlers lived there, and they built a church and a school. It's believed that this church was a stop on the Underground Railroad, a secret network that helped enslaved people find freedom.

Later, the post office moved several times. In 1853, a railroad station was built about 5 miles south of the original settlement. The name "Somonauk" then moved to this new location, where the village is today. It officially became a village in 1865.
