Brownsville (also Banjotown) is an unincorporated community and census-designated place in Washington County, Maryland, United States, near Gapland in an area known as Pleasant Valley.

[5] John Brown, son of Tobias, and his son Cornelius established a tannery in the swamp land at the head of a small tributary to Israel Creek, and built a home on the east side of the valley overlooking the tannery.

[6] He was succeeded on February 3, 1836, by John Brown, who was born near Brownsville, December 20, 1790, served as a soldier in the War of 1812 and saw action at the Battle of North Point.

[9] Cornelius's son, George T. Brown, was appointed to the post in February 1898 and held it for over 40 years.

Afterwards, it was burned by the Union Army to prevent Confederates from using the structure given its proximity to the border line at the Potomac River.
