Morris, Livingston County, New York, built in 1838 and attributed to Colonel Walker Hinman. It was the last home of General William A. Mills.","why_significant":"The house is tied to General William A. Mills, founder and first permanent white settler of Mt. Morris and a prominent public figure in Livingston County. It is also valued as a transitional building combining Federal (neoclassical) and Greek Revival forms, with good craftsmanship and a largely intact interior.","narrative":"Built in 1838, this brick house at 14 Main Street in Mt. Morris was the last home of General William A. Mills, who settled in the town in 1794 and later founded it in 1818 and Livingston County in 1821. The design is attributed to Colonel Walker Hinman, a friend of Mills. The two-and-one-half-story main block has a three-bay facade, an Ionic portico, double brick chimneys and stone-framed gable fanlights, blending Federal and Greek Revival styles. Inside, seventeen rooms retain bold Greek Revival moldings, cherry and walnut doors, and a cantilevered black walnut staircase. Later owners divided the house into apartments and used it as a warehouse. After standing vacant in the mid-1970s, it was bought by the local Rotary Club in 1976 and given to the Mt. Morris Historical Society. Restoration was under way for museum and educational use, and an archeological survey had uncovered a garden well and a rear brick path.","period_of_significance":"1800-1899","architect_builder":"Attributed to Colonel Walker Hinman","architectural_style":"Transitional Federal and Greek Revival","criteria":[],"status_note":"Vacant for over a year after 1975; bought in 1976 by the Mt.
