Darnall's Chance, also known as Buck House, Buck-Wardrop House, or James Wardrop House, is a historic home located at 14800 Governor Oden Bowie Drive, in Upper Marlboro, Prince George's County, Maryland, United States. It is named after Colonel Henry Darnall, a wealthy Roman Catholic planter, who was the Proprietary Agent of Charles Calvert, 3rd Baron Baltimore and who served for a time as Deputy Governor of the Province. The house itself was built c. 1742 by a merchant named James Wardrop who bought some of Darnall's land from Eleanor Darnall Carroll and her husband Daniel Carroll, a politician and wealthy planter. Wardrop enslaved 32 people at the house. Today, Darnall's Chance houses the Darnall's Chance House Museum, a historic house museum which opened to the public in 1988. History Origins The tract of land the house sits on was patented in 1704 by Col. Henry Darnall (1645–1711), a wealthy Maryland Roman Catholic planter, Proprietary Agent of Charles Calvert, 3rd Baron Baltimore and, for a time, Deputy Governor of Maryland. However, during the Protestant Revolution of 1689, Darnall's proprietarial army was defeated by the Puritan army of Colonel John Coode, and he was stripped of his numerous offices. When Col. Darnall died in 1711, he owned in Prince George's County, as well as holdings in four other counties. The property of what became known as Darnall's Chance passed through his family to his granddaughter Eleanor Darnall, who married Daniel Carroll I in 1727. Their family was reared on the large landholding and plantation. Two Carroll sons were prominent members of colonial and early United States society: Daniel Carroll became a politician in the Continental Congress and Maryland Senate, and member of the Constitutional Convention; and John Carroll became the first Roman Catholic bishop in the United States, and founder of Georgetown University. In 1741, the Carrolls sold 6 acres of their land to James Wardrop, a Scottish merchant. Wardrop built a 15-room brick dwelling house within a year, originally a -story, Flemish bond brick house. It is that house that currently stands on the property. After living at Darnall's Chance as a bachelor for six years, Wardrop married 22-year-old Lettice Lee, whose father, Philip Lee Sr., was a member of the Lee family of Westmoreland County, Virginia. Nineteenth century In the mid-19th century, the house was remodeled to two stories, of stuccoed brick, with Italianate and Greek Revival stylistic elements. The
