Gen. Mason J. Young House

The Gen. Mason J. Young House, also known as the William Boyd House, is a historic site located in Londonderry, New Hampshire, with origins dating back to 1802. This well-preserved example of a New England connected farmstead features a distinctive 2+1⁄2-story wood-frame structure, a columned portico, and a series of sheds linking it to a carriage house and dairy barn. Originally a subsistence farm, it evolved into a dairy operation in the mid-19th century and later shifted to apple production. The property has been in continuous family ownership for over 200 years and was recognized as a Bicentennial Farm in 1976, making it a fascinating destination for tourists and researchers interested in agricultural history and architecture.
