The Stagg Homestead was erected about 1812 by John C. Stagg on the site of an earlier building owned by his father, Cornelius Stagg, a veteran of the Revolutionary War. For many years, John C. Stagg operated a grocery store in the basement. His son, Albert, sold the property to Richard Terhune in 1846. Judge Nehemiah Millard, one of the area’s first railroad commuters to New York City, purchased the house in 1868. It was later owned by the MacDonald family.
