The area that later became Thiensville was first surveyed between 1834 and 1836, after the United States government removed Native Americans from the land. Weston built the first log cabin in the area, and became the area's first postmaster. He soon sold his land holdings to John Henry Thien.
John Henry Thien (or Jochim Heinrich Thien), was a wealthy German immigrant who had stopped in Milwaukee after leaving Saxony with his wife. They set on finding a place to live in this new area, and journeyed north in 1842. They eventually settled along the Milwaukee River, where Thien purchased 148 acres (0.60 km2) of land and founded Thiensville that same year.
In 1846, the Wisconsin Territorial government formed the Town of Mequon, with borders that included all of present-day Mequon and Thiensville. The first town meetings were held in Thien's home. Thiensville itself was incorporated as a village in 1910, with a population of 289.
