A final analysis of the physical evidence also shed light on why no ca. 1797 mantels were found during the investigation.  When the plaster was removed from the brick wall behind the mantel in the Large Bedroom, a large patch of whitewash was found surrounding the firebox.  The whitewash, along with a lack of evidence for the installation of a pre-1812 mantel, suggested that a ca. 1797 mantel had never been installed.  Furthermore, the chimney stack in the Dining Room also displayed evidence for only a single ca. 1812 mantel.
