William Murphy, arrived on the land west of the Mississippi River in 1798, when it was part of the upper Louisiana Territory and under Spanish rule. Calderon was searching for the ideal site to relocate his family and, as the tradition goes, came to find a spring near what is now the St. Francois County Courthouse with the aid of a local Native American. Deciding that this was an excellent place to set up home, Murphy acquired a Spanish Land Grant, allowing him and his family to establish a settlement along the St. Francois River.
