Beaver County was created on March 12, 1800, from the surrounding counties of Allegheny and Washington. The county was originally divided into six townships, which included Hanover Twp. and North Beaver Twp. On March 20, 1849, a section of Beaver County was used to help form present day Lawrence County. Rev. Joseph H. Bausman upon the occasion of the Beaver County’s Centennial Celebration in1900 wrote a history of Beaver County. His document reveals that the name “Beaver” was given to the county because of the stream and town, which were already named such. Historically, the stream’s name was a translation of the Native American word for beaver.
Beaver County is bordered by Lawrence County in the north, Allegheny County and Butler County, in the east, Washington County, in the south, and Columbiana County, Ohio and Hancock County, West Virginia in the west.
