25 Nov. 1819–17 Feb. 1886
In 1832 he received, by devise, from his great-grandfather the Cooleemee Plantation of 2,300 acres in Davie and Davidson counties, N.C., and, though only thirteen years old, took charge of its management. During his college years he continued to travel there and handle management problems. After leaving law school, Hairston began to assume other family responsibilities, including travel to Europe in 1842 in the hope of finding a cure for the illness of his younger brother George. His diary (unpublished) gives a detailed description of his journey and what he saw. He returned at the end of two years and became deeply engrossed in the management of the family estates. In 1849 he married Columbia Lafayette Stuart, a sister of James Ewell Brown ("Jeb") Stuart (the Confederate major general who commanded the cavalry of the Army of Northern Virginia).
Hairston's enslaved people increased crop production at Cooleemee, shipping tobacco, hogs, and cotton as far away as Petersburg, Va. The number of enslaved people on the plantation grew to 300. Between 1853 and 1855 he built the present plantation house, an Anglo-Grecian villa with a double spiral staircase, which stands today as an outstanding example of late Greek Revival architecture. At the time, the building of this house was a mammoth undertaking in Piedmont North Carolina.
As a director of the Yadkin River Navigation Company, Hairston participated in its effort to make that river navigable to the sea. The attempt was only partially successful.
In 1857 Columbia died, and in 1859 Hairston married Fanny M. Caldwell, daughter of Davie Franklin Caldwell, a Superior Court judge and bank director. The couple spent their honeymoon in Europe, returning just before the outbreak of the Civil War. The bridegroom immediately became a volunteer aide on Stuart's staff but soon found that family business required his presence at home. After a short stay, he joined the staff of General Jubal A. Early. Hairston's younger brother had died, his father was senile, and his grandmother was over seventy-five. The responsibility of looking after the combined estates, which involved managing the work of 4,000 enslaved people and thousands of acres during wartime, required many trips home from the front.
At the end of the war, the people formerly enslaved by Hairston remained on his property as hired help to till the soil of the plantation while he moved to Baltimore, Maryland, and carried on a business as a grain and fertilizer merchant until his death.
By his first wife Hairston had three children: Samuel, Betty, and Archibald. All of them died before coming of age. By his second marriage he had four children: Agnes W. (1861–1914); Frank Caldwell (1865–1902), sometime North Carolina senator; Ruth Wilson (1868–1947); and Peter Wilson, Jr. (1871–1943).
