Maps are wonderful and important resources for the genealogist. (These links were last verified as working on 12 December 1999.)

Are you asking yourself, "Why would I need a map of Washington Co.?"

  • To locate the name of a community in which your ancestors reportedly lived.
  • To help understand the shape, size, and location of your ancestor's land patent.
  • To determine the route your ancestors might have taken between their house of worship and their farm.
  • To find out who your ancestor's neighbors might have been. Those neighbors may end up being relatives.
  • To get a sense of the population and size of Washington Co. at various times in the past.
  • To figure out what roll of census microfilm to order and examine.

Maps are a concrete and fairly accurate representation of they way the world was at a given point in time, and therefore they help ground us in the reality of our ancestor's lives. This is very useful for genealogists, since we so often have to "fill in the blanks" and consequently run the risk of making too much up.

Different maps may best meet the varying needs outlined above, as you will find out in the rest of this page.

On-line - Caldwell's Atlas of Washington County published 1876. Courtesy of Clair John "Bill" Thompson, Sr. - 

Caldwell's Atlas is a wonderful genealogical tool because it contains a map for each township and borough of the era. The maps have churches and schools designated, and the names the owner of the farms in the townships. Plats of the many small communities also appear, with lots designated by owner.

Actual copies of the Atlas are available at the Citizens Library. Caldwell's Atlas is also available on microfilm which has been distributed to many major libraries.

Additionally, the atlas lists contributors by township. A large number of citizens contributed and therefore you may also find out how many acres were in their holding, what their major crop or stock interests were, and when they settled in the county, etc.

Finally, numerous pen and ink drawings are interspersed throughout the atlas including:

  • Homesteads and farms from throughout the county
  • Major government buildings
  • Stores and commercial buildings
  • Churches and schools

Pennsylvania Land Warrant Maps

These maps show the original warrants and patents for each township. You can obtain them from the Pennsylvania Histoical and Museum Collection. Also, the genealogical section of the Citizens Library has reduced size copies that may be photocopied for your personal use.

See the land purchase page to gain an understanding of what the information on these maps means.

Information on these maps includes:

  • Original boundaries of land grants
  • Name of the person to whom land was warranted
  • Date of warrant
  • Acreage

The maps are produced by the diazo blue process and their size varies from 22" x 30" and upward. Prices start at about $5 each and varies depending on the number of tracts in the amp. For Washington County, maps average 77 tracts (ranging from 44 to 148).

Township zoning maps.

These maps, in addition to zoning boundaries, contain current property boundaries with notations of acreage and owner. If you find yourself having to work backwards through the county deed books, this is an excellent place to start since deeds back-reference the previous owner.

The maps also reference local roads by name that otherwise show up only by road number on other maps.

Purchase zoning maps from the municipal governments for which they are produced.

Current land plat maps.

The tax assessor needs to know who owns what land, so at the County Assessor's office you will find plat books showing current ownership. The County Tax Assessor's office can be reached at (412)228-6850.
