Butler County, PA History

Butler County was formed from the county of Allegheny, by the act of the 12th of March, 1800, and named in honor of General Richard Butler, who was killed at St. Clair's defeat. It was then bounded: "Beginning at the mouth of Buffalo Creek, on the Allegheny river; thence by a straight line running due west until it strikes the line on Beaver county; thence north by the line of said county to the north-east corner of said county; thence by a line north thirty-five degrees, east fourteen miles; thence by a line running due north from the mouth of Buffalo creek, the place of beginning." The place of the county seat was not to be at a greater distance than four miles from the center of the county. The year following commissioners were appointed to run the county lines. The persons appointed for this purpose wee Samuel Rippy, Henry Evans, and John M'Bride, and Beatty Quinn as their axeman. After these commissioners had performed their duty and made the proper report, the Legislature appointed John David, William Elliott, and Samuel Ewalt, commissioners to fix upon a proper place for the seat of justice for the county. The place selected by them is where the town of Butler now stands.

While this county was still a part of Allegheny County it contained but four townships. These were Buffalo, Middlesex, Conoquenessing, and Slippery Rock. The limits of the county now are as follows. Beginning at the mouth of the Buffalo creek at Freeport; thence westward twenty-three mile to a corner of the west side of Alexander's district, adjoining Beaver county; thence along said line and Beaver County, northward twenty-three miles to a corner, where the streams of Muddy creek and Slippery Rock unite; thence along the Mercer county line north fifteen degrees, east fifteen miles to a corner near Harrisville; then eastward fifteen miles to a corner near the Allegheny river near Emlenton; thence southward about thirty miles along the Armstrong county line to the place of beginning, containing about seven hundred and eighty-five square miles.
