It also represents the Whallon family, a pioneer family active in farming, religion and education whose substantial home reflects their success.","narrative":"Built about 1816 on one of the highest points in the area, this two-story red brick house on Winton Road in Greenhills was constructed by James Whallon, who fired the bricks on the site. The west facade is laid in Flemish bond, with gauged brick over the windows and a doorway featuring sidelights and a delicate elliptical fanlight. Inside, carved elliptical motifs repeat on the mantels, and the entry hall keeps its original open-string stair with a cherry handrail. Whallon arrived in Ohio in 1800, farmed the land, served as Justice of the Peace and raised a devout Presbyterian family that produced several ministers. The house is regarded as a fine and uncommon local example of Federal architecture. The City of Greenhills bought it in 1958 and has used it for municipal offices, scouting and church services. Some alterations have occurred, but it retains its early character.","period_of_significance":"19th Century (c. 1816)","architect_builder":"James Whallon (owner and builder)","architectural_style":"Federal (American Federal period)","criteria":[],"status_note":"Owned by the City of Greenhills since 1958 and in good condition; used for a city engineering office and license bureau, by a Girl Scout troop, and on Sundays by a Baptist church.
