Researching Your House (House Genealogy)



  • If your house is one or two stories tall with rafters showing below the roof, it may be a bungalow built from 1905-1930.
  • Is your house two stories with a gable facing the street and a side wing? This house is a vernacular farmhouse (1850-1890) also referred to as a folk or front gable and wing house.
  • ls your house three stories tall with an asymmetrical facade, steeply pitched roofs and a porch? This is a Victorian house built between 1860 and 1910.
  • A Greek revival may have columns, a Gothic revival has fall pointed gables and an Italianate house (1840 - 1885) has wide overhanging roof eaves supported by decorative brackets. You might own a Colonial, Dutch Colonial or Cape Cod. Occasionally styles are mixed or renovations disguise the original house. An Italianate house may be a front gable and wing house and a farmhouse may be dressed up as a Victorian.
