On June 20, 1632, Charles I of England (ignoring Native American land claims) gave of land covering most of what is now the modern U.S. state of Maryland to Cecil Calvert, 2nd Baron Baltimore as a proprietary colony. The charter had originally been granted to Calvert's father, George Calvert, 1st Baron Baltimore, but the 1st Baron Baltimore died before it could be executed, so it was granted to his son instead. On September 4, 1663, a land patent was issued to Thomas Dent, Sr. for a tract known as "Gisbrough". This tract was roughly in the area that is now Joint Base Anacostia–Bolling between Malcolm X Avenue SE/MacDill Boulevard SE and Giavannoli Street SW, the northern end of Bellevue, and the southern end of Congress Heights. On September 7, a land patent was issued to William Middleton for a tract known as "Berry". This smaller tract covered what is now the southern end of Joint Base Anacostia-Bolling and the southern part of Bellevue.
