It is now part of Saint Casimir's Roman Catholic Church complex.","why_significant":"The nomination presents the mansion as an architecturally and historically significant example of an Italian Villa and one of the few surviving mid-nineteenth-century buildings in Yonkers. It is tied to John Copcutt, an early industrialist whose arrival in 1845 helped turn Yonkers from an agricultural village into an industrial center. The interior retains finely detailed period decoration. It is also linked to Dr. Charles Leale, who married Copcutt's daughter in the house and was the first surgeon to reach President Lincoln at Ford's Theater.","narrative":"Built in 1854 for John Copcutt, a veneer manufacturer who became the largest dealer in imported woods in the United States, this granite mansion at 239 Nepperhan Avenue in Yonkers is an Italianate villa with a cruciform plan and a projecting central tower. Round-arched and pedimented windows, bracketed eaves and rusticated stonework mark its style. Inside, a stair hall with a elliptical light well, fluted Composite columns, plaster moldings and marble mantels survives largely intact. Copcutt's mills made up one of the earliest major industries in Yonkers, and this house is the only remaining building connected with him. Dr. Charles Leale, who attended President Lincoln, married Copcutt's daughter here. The church bought the property in 1900, used it as a convent from 1910, and has used it as a rectory since. The tower's top story and part of the front porch have been removed, but the exterior is otherwise largely unchanged. Only one other comparable Italianate villa remains in the city.","period_of_significance":"1800-1899 (specific date circa 1854)","architect_builder":null,"architectural_style":"Italianate (Italian Villa)","criteria":[],"status_note":"Occupied and in excellent condition; used as a rectory by Saint Casimir's Church.
