The Miller-Cory House is a story-and-a-half clapboard farmhouse with shingled roof, brace and beam construction, and nogging-filled walls typical of an average New Jersey homestead of the mid-18th century. It was begun in 1740, at the time Samuel Miller married his wife Sabra. Three sections were completed before Samuel Miller's death in 1782. The property came into the possession of Joseph Cory in 1784, and remained in the Cory family until 1921. Today, the Miller-Cory House is a nationally recognized living museum.
