Lawrence County, Ohio

Lawrence County is the southernmost county of the U.S. state of Ohio. As of the 2020 census, the population was 58,240. Its county seat is Ironton. The county was created in 1815 and later organized in 1817. It is named for James Lawrence, the naval officer famous for the line "do not give up the ship". Lawrence County is part of the Huntington–Ashland metropolitan area.

The earliest European-American settlers, Luke Kelly and his family, and May Keyser, settled at Hanging Rock along the Ohio River in 1796, having migrated from the east. Lawrence County was formed on December 20, 1816, from parts of Gallia and Scioto counties, with the county seat named as Burlington. In 1851, the county seat was moved from Burlington to Ironton. A new courthouse was built at that time. It burned in 1857. The present Lawrence County Courthouse was built in 1908.

Men from Lawrence County served in the Mexican–American War, with at least one having died during that conflict. By 1862, about 3,200 of Lawrence County's men were soldiers in the Union Army in the American Civil War. During World War I, 2,200 of Lawrence County's men served in the armed forces, and 99 died.

As of the 2010 United States census, there were 62,450 people, 24,974 households, and 17,405 families living in the county. The population density was 137.7 inhabitants per square mile (53.2/km²).

In Lawrence County, less than 1% of people who self-identify as "Irish" are Catholic. Scholars believe this is part of a trend in which people are vaguely aware that at least some of their ancestors come from Ireland, but that population is primarily of "Scots-Irish" or "Ulster Scots" ancestry, and those identifying as "Irish" are simply unaware of the distinction. Those citing "American" ancestry in Lawrence County are of overwhelmingly English extraction, most English Americans identify simply as American because their ancestors have been in North America for centuries—in some cases since the 1600s.
