The first settlement in Fort Jennings was made around 1850. Fort Jennings took its name from Col. William Jennings, who established a fort near the site in 1812. The village was founded in 1847 and incorporated in 1881.
The town of Fort Jennings was laid out by H. J. Boehmer and takes its name, as well as the township, from Colonel Jennings, who was the commandant of the fort—a small stockade, enclosing about one acre of ground, on the west bank of the river, and below the bridge. There was then a fine spring on the river within the enclosure, which .was occupied in the war of 1812 as a military post.
