[3] The Village of Brownsville was first known as Thetis Station and had a narrow gauge railroad connection to Fond du Lac and Iron Ridge.

As the town became more established towards the turn of the 20th Century, additional businesses and agricultural infrastructure were built, including crop storage bins and a grain elevator.

In 1902 a small factory was built in town where it was used in local cheese production by various owners until the building was purchased by Michels Corporation in 1965, and demolished in 1973.

They built their first church building in 1887, which was located on Main Street next to the current cemetery until it was destroyed by a fire on September 6, 1909.

The same year as the construction of the first church, the congregation elected a local Mr. Gottmanshausen as its first pastor, who accepted the call of the community.

The tornado uprooted trees, tore siding off from buildings, damaged roofs, and downed power lines, among other destruction.

The village was put under a state of emergency, with residents only being allowed in days after the tornado.

Kummel Creek, a tributary of the Rock River, begins just north of the village, through which it flows, and the Horicon Marsh sits approximately five miles west of the town.

According to the United States Census Bureau, the village has a total area of 0.52 square miles (1.35 km2), all of it land.

Brownsville contains a variety of businesses, including a bowling alley, a bar and grill, an apple orchard, a bank, a gas station, a dentist, and a medical clinic affiliated with SSM Health and Saint Agnes Hospital in Fond du Lac.

Public amenities include the local public library, two parks, baseball/softball diamonds and soccer fields, and a community center that functions both as a hub for community events as well as a rentable space for private events.
