What stands out about Clinton Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The community of Bloomington was settled in June 1854, but was not known as such until April 1855, when Harrison Burson applied to the U.S. Government for a post office. Within eight months of the area being settled, some 530 settlers were in the area that would become Bloomington-Clinton. The people of Bloomington were greatly anti-slavery and helped slaves escape through the Underground Railroad. In early 1857, the northern half of Bloomington was moved to a new location and the southern portion of the community was renamed Winchester.
