Jonathan Boucher (1738–1804) of England came to the United States in 1759, but two years later went to London to obtain ordination as an Anglican minister, which he received in January 1762.  Boucher subsequently served  as a clergyman in Virginia and Maryland. He was rector of Hanover Parish, Va., and then of St. Mary's Parish in Caroline County, Virginia. Boucher, in 1770, was appointed rector of St. Anne's Parish in Annapolis, Md., and one year later received a similar appointment at Queen Anne's Parish in Prince Georges County, Md., which position he held until 1775. At the outset of the Revolutionary War, Boucher became a Loyalist, and in September 1775, he fled to England, where he lived for the remainder of his life. Boucher continued to serve as an Anglican clergyman, and was vicar of Epsom parish in Surrey, England, from 1785 to 1804.   

Boucher was a frequent correspondent of GW from 1768 to 1773, during which time he was John Parke Custis’s schoolmaster.
