Tradition dates it to 1803, with a rear addition traditionally dated 1812.","why_significant":"The form describes it as a very early pioneer house with several features drawn from mid-Atlantic rather than New England building practice, such as the continuous-rafter two-story porch and the stair behind the central chimney. It is also tied to Conrad Neff, an early settler and mason, and to its later use as a tavern on a main Pittsburgh to Cleveland road.","narrative":"Built about 1803 near Canfield, this two-story log house is covered in hand-sawn clapboard siding. Squared walnut logs form the walls and can still be seen in the attic, while corner posts show in the interior rooms. The original plan had four rooms, two on each floor, around a central chimney, and the two-story front porch is original because its roof rafters run continuously with the house's. The porch, the stair set behind the chimney stack and other details follow mid-Atlantic rather than New England tradition. A one-and-a-half story rear wing, traditionally dated 1812, holds a large open cooking hearth. Conrad Neff, a mason who came from Berks County, Pennsylvania, in 1802, built a log house on the site while his sons cleared and farmed the land. In 1826 the house was sold to Jacob Barnes, who ran a tavern there for many years on a main Pittsburgh to Cleveland road.","period_of_significance":"19th Century (specific date 1803)","architect_builder":"Conrad Neff (mason, documented as erecting a log house on the property)","architectural_style":null,"criteria":[],"status_note":"Listed in good condition, altered, on its original site; private residence, occupied.
