History
The Osage peoples were the first people that lived in what today is Arnold, many artifacts have been found in the area that show there was an ancient Osage village near where the Meramec River meets the Mississippi River. In the area where 2 salt licks used to be, human bones have been found, along with pottery shards and many other artifacts. The first European settler in Arnold, was John Hildebrand an immigrant from Germany, that lived in Monongahela County, Pennsylvania. He was the first white settler in the area that is today Jefferson county, he established a settlement near saline creek, with a fort for protection. In 1776 French Canadian settler Jean Baptiste Gamache, who operated a ferry boat across the Meramec River was granted 1050 arpents of land by King Charles III of Spain. This ferry was on the King's Trace or El Camino Real, from St. Louis to Ste. Genevieve, Missouri.[1] [2]
