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.

Some early maps are the best source for discovering previous occupants of your house. These maps include names of property owners and indicate how Patchogue appeared before the addition of new streets and land subdivisions:

  • Patchogue-Medford Library's Map Collection
    The Patchogue map drawer in the local history room has Patchogue street maps dating to 1812. The Beers Atlas maps (1853, 1873 and 1888), the Chase Wall Map (1857) and the Hyde Atlas map (1915) list homeowner's names.


If a search through Patchogue maps resulted in the name of a prior owner, that name can be searched in the following sources:
