History The area of Upper Marlboro was first settled around 1695. It was named after John Churchill, 1st Duke of Marlborough , an ancestor of Winston Churchill . The land, which was to become the town, was part of several estates known as Grove Landing, Meadows, and Darnall's Chance, owned by the Brooke, Beall, and Darnall families, respectively. Darnall's Chance , also known as the Buck House, was built between 1694 and 1712. The house can still be found across from the present-day County Administration Building on Gov. Oden Bowie Drive. It was owned by the Darnall and Carroll families. The home may have been the birthplace of Daniel Carroll , a signer of the US Constitution , and his brother, John Carroll , the first bishop of the Roman Catholic Church in America.
