The Joseph Abercrombie includes characteristics of several early architectural styles. The main mass of the front is Greek revival. Note the heavy corner boards and the wide frieze under the roofline. The back elevation is Cape like, with three dormers.
The barn connector and the bedroom wing and porches perhaps were added over time as the family grew and could afford more space and comforts. The resulting rambling farmhouse looks as though it has occupied this place for many years.
