Located in the heart of Petit Village Francois, this house was built by Laurent Etienne Pensoneau in 1818. He was the son of Etienne Pensoneau who built the first official St. Clair County Courthouse in 1817. Laurent's bride was a descendant of Jean Baptiste Saucier, the designer of the second Fort de Chartres.
