Bordley, John Beale (11 February 1727–26 January 1804), agricultural theorist and lawyer, was born in Annapolis, Maryland, the son of Thomas Bordley, a lawyer, and Ariana Vanderheyden Frisby. At the age of twenty-one, Bordley inherited land from his father. In 1751, after his marriage in that year to Margaret Chew, this property was combined with the private fortune of his wife, and he devoted considerable effort to tending his estate near Joppa close to Baltimore. The couple had four children. Bordley also studied law in the office of his brother Stephen, and in 1753 he was appointed prothonotary (chief clerk) of Baltimore County; he simultaneously established a law practice that encompassed Cecil County, Harford County, and Baltimore County. In 1765 Bordley resigned his clerkship in protest of the Stamp Act and moved his law practice to Baltimore, where he soon attracted such renown that in 1766 he was appointed judge of the Provincial Court of Maryland and in 1768 a member of the commission to determine the line between Maryland and Delaware....
