Cottleville is one of the oldest towns in St. Charles County. The town was first settled by Captain Warren G. Cottle in 1798 under a Spanish land grant.[4] The area saw little development until 1810 when the John Pitman family arrived. Captain Cottle died in 1811, and his son, Dr. Warren G. Cottle Jr., inherited the farmlands. Dr. Cottle farmed extensively and occasionally practiced medicine. His son, Lorenzo, inherited 200 acres on both sides of the Dardenne River and, in 1839, parceled and named the town Cottleville after his father and grandfather. Before this, the village was known as Dardenne or Pin Hook. Early settlers included George Huffman (before 1803), Aaron Rutger (before 1809), Nathaniel Simons, and Nicholas Contz.[5] A post office called Cottleville has been in operation since 1843.[6] The town site was laid out in 1839.[7]
