Brent was born at Port Tobacco, Charles County, Maryland, on February 20, 1784, the first child of Robert Brent and Dorothy Leigh Brent. His father's family had owned land in that area of Maryland since about 1640, but some had fled to Virginia before the American Revolutionary War. His maternal grandfather, William Leigh, owned St. Bernards, a plantation near the Port Tobacco River at Pomonkey, which he gave to Robert and Dorothy when they married. Robert Brent built a house which he named Brentfield. However, because William Leigh Brent married a local heiress, his father secured William's consent to leaving it to his younger brother, George Brent, who became a Judge of Maryland's Seventh Judicial District and of the Circuit Court of Appeals. Virginia congressman and Senator Richard Brent was a paternal cousin. Another paternal cousin was Robert Brent, who became the first mayor of Washington, D.C. and freed his slaves in his will. William Leigh Brent studied law and was admitted to the bar of Maryland. In 1809 he married his first cousin Maria Fenwick, with whom he would have nine children.
Career
William Leigh Brent and his new wife soon moved to Louisiana, where Brent began his legal career. President James Madison named him Deputy Attorney General for the western district of the Territory of Orleans. After the international slave trade became illegal, many Maryland and Virginia-born enslaved people were shipped through Port Tobacco to the sugar plantations of Louisiana; prosecuting fugitive slave cases was part of his job. In 1822 Brent was elected as an Adams-Clay Republican to the Eighteenth Congress and moved to Washington, D.C. The following year, his father-in-law died and he and Maria inherited an estate called Pomonkey on the creek of the same name near a village called Fenwick. W.L. Brent remained in Washington and Maryland until 1844, when he returned to Louisiana. He was Louisiana's representative in Congress from March 4, 1823 until March 3, 1829, having been elected as an Adams Republican to the Nineteenth, and Twentieth Congresses. Representative Brent was a founding member of Louisiana's Whig Party, but was not again a candidate for public office. His successor was Jacksonian Democrat General Walter Hampden Overton, whose family had moved from Virginia when he was young, who became a war hero at the Battle of New Orleans and whose daughter married one of W.L. Brent's sons. As his political career ended, Brent resumed the practice of law in Louisiana and in Washington, D.C..
Death and legacy
Brent died in St. Martinville, Louisiana, on July 7, 1848. He is buried in St. Martin’s Catholic Cemetery. An inscription on his gravestone indicates his especial popularity with the Acadian population of Teche Bayou in St. Martin Parish. Four of their sons became lawyers and politicians, and probably supported slavery. Their eldest son Robert James Brent remained in Maryland, having married Matilda Lawrence of Hagerstown, Maryland. He practiced law in Baltimore and Washington, D.C. and was the last Attorney General under the Maryland constitution replaced in 1851. Another son, James Fenwick Brent became a prominent lawyer in Louisiana, and married the daughter of General Walter Hampden Overton. He predeceased his father. Another son, Joseph Lancaster Brent, became a lawyer after studying at Georgetown University, married a Louisiana heiress, served two terms in the California legislature, then returned to serve in the Confederate Army as Major. After the American Civil War, Joseph L. Brent returned to Louisiana to manage his wife's estates and served two terms in the Louisiana legislature. The youngest son, Charles Vivian Brent was born at Pomonkey and married a daughter of Maryland Senator William D. Merrick. Although their children died young, C.V. Brent edited the Southern Maryland Independent newspaper as well as practiced law with his elder brother Robert in Baltimore. C.V. Brent also served in Maryland's post-war Constitutional Convention, and then was a lawyer in the U.S. Department of the Interior Interior Department until his death in Georgetown.
