Southwestern Pennsylvania

The southwestern corner of Pennsylvania is the area that was the original Washington County, formed on March 28, 1781. This is the land to the west of the Monongahela River, from the West Virginia line north and west and south of the Ohio River to the Ohio line. 

Parts of the original Washington County are now Greene and portions of Beaver and Allegheny Counties. Both Pennsylvania and Virginia initially claimed this Southwestern Pennsylvania portion of the Commonwealth.

The first National Road, Route 40, came through our area, along with endless visits by the famous surveyors George Washington, Lafayette, George Rogers Clark, James Monroe, Andrew Jackson, and many other renowned people.

Join Western Pennsylvania and Pittsburgh Museums to learn more about the county's notable ancestry—and possibly your own.
