H. Gilbert identified as the builder.","why_significant":"The house is significant for its architecture, which reflects a transition from late Federal to early Victorian style. It is also tied to the Anderson family and the Anderson-Shaffer Company, a major milling, grain and coal business in Hamilton. It anchors a historic residential neighborhood on the city's west side.","narrative":"Built in 1859 at 404 Ross Avenue in Hamilton, Ohio, this red brick house combines late Federal restraint with early Victorian details. It has a modified T-shaped plan, a slate gable roof, symmetrical 6/6 windows with ogee arched stone lintels, and a bracketed cornice. The recessed entrance has ten-foot wooden double doors beneath a wrought iron portico with a vine motif. Inside, a cherry and mahogany stairway is stamped with the name of carpenter and brickmason P. H. Gilbert. Daniel Rumple, a farmer turned hardware merchant, had the house built. After his death in 1864 it was bought by Rachel Anderson, wife of miller and businessman William Anderson. Anderson's leather, milling and grain interests grew into the Anderson-Shaffer Company, which expanded under his son-in-law George K. Shaffer into a large regional wholesale dealer in coal, flour and feed. The house stayed in the Shaffer family for generations and remains the focal point of a quiet west-side neighborhood near one of the old family mills.","period_of_significance":"19th Century (1859)","architect_builder":"P.
