Arnold, Jr.","why_significant":"The nomination argues the house is an example of a distinctive local building type: story-and-a-half braced frame construction with a rear wing, cut stone set on edge across the foundation, pre-Victorian detailing and a tiger maple stairway. Its tiger maple staircase and paneling are called the most magnificent example found to date. It is also tied to Diadatus Keeler, an important local farmer who introduced new strains of sheep and hogs.","narrative":"Southeast of Galena in Delaware County, Ohio, this 1 1/2 story braced frame farmhouse was built for Diadatus Keeler and completed by 1833. An L-shaped building with clapboard siding, a gable roof and a classically pedimented front porch, it rests on a foundation fronted by cut stones set on edge. Inside, the stairway, banister and wall paneling are tiger maple, the woodwork is black walnut and the floors are ash. The house is considered a fine example of a local building type found mainly in eastern Delaware County and northeastern Franklin County, and is attributed to master carpenter Randall R. Arnold, Jr. Keeler, a Vermont native who settled the farm in 1819, introduced new strains of sheep and hogs to the township and helped organize its Presbyterian church. Later changes include the porch, added before 1900, a revised cornice, and dormers added in the 1930s.","period_of_significance":"1800-1899","architect_builder":"Attributed to Randall R.
