Pomonkey is named for the Pamunkey tribe of Native Americans that lived in the area. The Brent family owned much of the land from before the American Revolutionary War, asserting their claims after Giles Brent married princess Mary Kittamaquund in the 17th century. Robert Brent (1764-1819) became the first mayor of Washington, D.C. (and freed his slaves in his will).[5]
In the early 19th century, the village of Bumpy Oak was renamed Pomonkey when it was designated a postal stop.[6] Another Robert Brent (1759-1810) and Dorothy Leigh Brent built a plantation house in this area, which they called Brentfield (which later burned down).[5] Their children included Maryland judge George Brent (1817-1881) and Louisiana's U.S. Representative William Leigh Brent (1784-1848), one of whose sons became Maryland Attorney General Robert James Brent[7] and another Confederate General Joseph Lancaster Brent.[5][8][9]
The former Pomonkey High School was one of two black segregated high schools in Charles County until the 1960s, and has a proud alumni association.[10] From 1946 to 1970 the "Pomonkey Spoon Factory" manufactured wooden tools and small items.[11] In 2022, the Pomonkey High School Alumni Association held a Centennial Celebration which celebrated its 100 years of history including the fact that it was the first high school in the county created for black students.[12][13]
For several years, Maryland Airport has planned a 1,300 ft (400 m) expansion, including an energetics (explosives) technical center and business park employing over 3,000 people. However, environmental concerns related to stormwater discharge into Mattawoman Creek delayed those plans.[14] The Naval Research Laboratory has its Free Space Antenna Range on Bumpy Oak Road.[15][16][17]
