premise: Ashcroft is a historic home located at Geneva in Ontario County, New York. It is a 2 ⁄ -story brick home with a high pitched slate roof with projecting eaves. It is a large Gothic Revival style country house set deep in the midst of once carefully landscaped grounds. The house and property were designed by Calvert Vaux in 1862.
hypothesis: Ashcroft home was built before 1859.
reason: It was designed in 1862, so it couldn't have been built before that. I guess design/build is muddied.
