[4] Van Horn built a gristmill and was the first builder of a wool mill in Niagara County, New York in 1842.

Douglas Patterson of Nova Scotia, Canada, purchased the mansion in 1929 after a short ownership by the Cramer Brothers.

Mary Wagner in 1949 received the mansion and helped to renovate it for an upscale restaurant known as Green Acres.

It has held Victorian teas, tours, and underwent numerous volunteer renovation programs over the years.

The Van Horn Mansion is one of several haunted locations in Niagara County and Western New York.

During renovations roofers witnessed faces in windows of the vacant mansion and saw lights flicker for no reason.

The grave of Malinda, wife of James Van Horn Jr, is located in the rose garden on the south side of the grounds.

The bones of Malinda have since been moved to a small area in the backyard of the mansion and no other paranormal encounters have been made.
