The town of Franklin was founded by European Americans in 1816 and named for Founding Father Benjamin Franklin of the United States. William Becknell, who is now known as the "Father of the Santa Fe Trail," lived on a farm a few miles northwest of Franklin. There was a spring near Becknell's property, Boone Lick Spring.
The spring had saline water and attracted people from St. Louis and points east, who came to distill the water for its salt. They came so often that they created a trail, calling it Boone's Lick Road. "Boone" refers to Nathan and Daniel Morgan Boone, sons of explorer Daniel Boone. The brothers first operated the saltlick business.
