Cheboygan was originally a Native American settlement. In 1844, Jacob Sammons, a cooper from Fort Mackinac chose the old native camping ground (then called "Shabwegan") as the site for his cabin. He recruited other settler and a post office named "Duncan" was established in 1846. The name changed to Cheboygan in 1870 and was incorporated as a village in 1871 and as a city in 1889.
