Kensington’s history began as Joseph’s Park through a land grant of 4,220 acres, located at the time within Charles County, to Mr. William Joseph in 1689. Permitted on September 25, 1705, and now within Prince George’s County, William Joseph’s son used the land for agriculture until he sold it in 1736 to Mr. Daniel Carroll of Upper Marlboro. Carroll, who was one of only five men to sign both the Articles of Confederation (1777) and the Constitution (1787), sold various parcels of land to local farmers. Kensington’s current day form came about from Mr. George Knowles’ property following the construction of the Metropolitan Branch line from Washington, DC to Point of Rocks in 1873.
Bisecting Mr. Knowles’ property, the train began stopping in 1891 at Knowles Station to participate in commerce with Mr. Knowles and the other local farmers. Taking this into account, Mr. Brainard Warner purchased property south of Knowles Station in 1890 from the Brown family and built a summer retreat home. Mr. Warner then began encouraging his friends to purchase parcels of land from him so that they could build summer homes as well. Mr. Warner’s property became known as a “garden suburb” in which he designed after Kensington, England.
