The Warner Farm House was the home of Alanson Warner and his wife Catherina Albright. Alanson, the son of Andrew and Chloe Fairman Warner and a native of Worthington, Massachusetts, came to Ontario in 1816 with his parents. He was credited with inventing the differential, a device that allowed one wheel to turn faster than the other wheel, and his mowing machine could turn corners smoothly without losing power or dragging the outside wheel. Before the development of the automobile, he lost interest in the invention and sold the patent for $16.00. He also invented a pump system to bring water from the lake to the cistern in the basement, and the small back room by the basement stairs had a dry sink and a pump to bring the water upstairs. Alanson and Catherine's son, John Albright Warner, was born in Ontario on August 12, 1835, the third of eleven children. He was educated in Walworth and Macedon Academies, worked as a carpenter for 33 years, and owned a 97 acre farm with 15 acres of orchard and six acres of berries. A granddaughter remembered visiting the house and described the fruit drying operations. John invented his own apple corer and peeler. In 1860, he married Harriet Morris and they had six children. His son, Clarence, made a model voting machine. The one story house was built in 1838 as a simple two room structure from used materials and had a loft. Around 1868, a two story addition was added as the family became more prosperous and larger. The house was originally located at the intersection of Furnace Road and Lake Road, and it cost $20,000 to move it. In July 1991, the house was donated to the Historical Society by Mr. and Mrs. Jim Hollingsworth.
