Butler County, Pennsylvania: A Genealogical Overview

As one of western Pennsylvania’s historically significant counties, Butler County boasts a rich heritage rooted in pioneer settlement, agricultural growth, and industrial innovation. Its formation during the early 19th century and its role in the nation’s early oil boom provide a unique backdrop for genealogical research.


I. County Formation and Evolution

Understanding Butler County’s creation is crucial for locating the earliest records of its inhabitants.

  • March 12, 1800: County Created: Butler County was officially created by an act of the Pennsylvania General Assembly from a portion of Allegheny County. The town of Butler was designated as the county seat.
  • 1803: County Fully Organized: Although created in 1800, the county government was not fully organized until 1803. The first courthouse was constructed shortly thereafter.
  • Original Townships: The county was initially divided into thirteen townships: Buffalo, Butler, Connoquenessing, Cranberry, Donegal, Middlesex, Muddy Creek, Parker, Slippery Rock, Mercer, Centre, Venango, and Clearfield. Many of these have since been subdivided into the county’s current townships and boroughs.

Summary for Genealogists:

  • Before March 1800: Your ancestor lived in Allegheny County, PA. All land, court, and probate records from this period will be found there.
  • After March 1800: Records were created and are held by Butler County, PA, with the government becoming fully functional in 1803.

II. Settlement and Early History

  • Early Inhabitants: The region was originally the territory of various Native American groups, most notably the Seneca of the Iroquois Confederacy, as well as the Lenape (Delaware) and Shawnee.
  • Pioneer Settlement and Agriculture: Following the American Revolution, the area was opened to settlement, with many veterans of the war receiving land grants. The earliest settlers were predominantly Scots-Irish, German, and English pioneers who cleared the dense forests to establish farms. The economy was overwhelmingly agricultural for much of the 19th century.
  • Oil and Industrial Boom: The discovery of oil in the latter half of the 19th century transformed Butler County’s economy and landscape, bringing a new wave of migration and prosperity. The city of Butler became a major hub for manufacturing, home to the American Bantam Car Company, which created the prototype for the military “Jeep,” and Pullman-Standard, a major railroad car manufacturer. This industrial heritage defined the county for much of the 20th century.

III. Genealogical Records and Resources

This section provides the practical information needed to locate ancestral records specific to the county.

  • Courthouse and Government Center: Records are maintained by various offices within the county government.

    • Prothonotary: Holds civil court records, including naturalization records prior to 1906.
    • Recorder of Deeds: Holds all land records (deeds, mortgages) for the county from its formation.

Records from that date forward are held by the Pennsylvania Department of Health, Division of Vital Records in New Castle, PA. The county has scattered records for the period 1893-1905.
    • Marriage Records: Official county-level marriage licenses began in 1885. Records from that date forward are held by the Clerk of Orphans’ Court at the county courthouse. Prior to 1885, marriages were recorded in church records, newspapers, or dockets of Justices of the Peace.
