History
Lawrence County was created on March 20, 1849, from parts of Beaver and Mercer counties due to the rapid growth of New Castle, which was primarily in Mercer County but was rapidly expanding into Beaver County. The former borders between Beaver and Mercer Counties are still evident in Lawrence County today, as the northern borders of North Beaver Township, Shenango Township, and Slippery Rock Township with (respectively) the southern borders of Mahoning Township, Hickory Township, and Scott Township make up the former boundaries between Beaver and Mercer Counties. In addition, County Line Road in New Castle where the Lawrence County Courthouse is located also marks the former boundaries.
The county was named after the flagship of Commodore Oliver Hazard Perry, the USS Lawrence, which was disabled in the 10 September 1813 Battle of Lake Erie during the War of 1812. The ship’s complement included local raw recruits. That niagara-class brig (more correctly: snow) was itself a namesake, of Perry’s friend and naval officer James Lawrence, who died during the War of 1812.
