Question: In which state is Upper and Lower Marlboro located?
Context: Grahame House, Graham House, Mansion House, Graeme House, or Patuxent Manor, is a historic home located at Lower Marlboro, Calvert County, Maryland.  It is an 18th-century original 1 ⁄ -story brick shell laid in Flemish bond with a steeply pitched gable roof.  Later alterations have included the purchase and removal of the fine paneling throughout the house to the Henry Francis du Pont Winterthur Museum.  Charles Grahame, for whom the home is named, was associated with Frederick Calvert, sixth Lord Baltimore, through Grahame's brother, David Grahame (who married Calvert's cousin, Charlotte Hyde) and with Thomas Johnson, first elected Governor of the State of Maryland, through Grahame's son (who married Johnson's daughter). Maryland Route 725 (MD 725) is a state highway in the U.S. state of Maryland.  The state highway runs 1.86 mi from Brown Station Road east to U.S. Route 301 (US 301) within Upper Marlboro.  MD 725 is the old alignment of MD 4 through the county seat of Prince George's County.  What is now MD 725 was constructed in the mid- to late 1910s and became MD 4 in 1927.  After MD 4 bypassed Upper Marlboro in the early 1960s, the old highway through town became part of MD 408.  After the Prince George's County segments of MD 408 were removed in the late 1970s, the remaining state-maintained highway through Upper Marlboro became MD 725. Lower Marlboro, Maryland (not to be confused with Upper Marlboro, Maryland, which is approximately 15 miles north) is a small, waterfront unincorporated community located at the crossroads of MD 262 and Chaneyville Road in Calvert County, Maryland along the Patuxent River. Maryland Route 202 (MD 202) is a state highway in the U.S. state of Maryland.  The highway runs 13.92 mi from MD 725 in Upper Marlboro north to MD 450 in Bladensburg.  MD 202 connects the central Prince George's County communities of Bladensburg, Cheverly, Landover, and Largo with the county seat of Upper Marlboro.  The state highway was constructed from Bladensburg to Largo in the mid- to late 1920s and from Largo to Upper Marlboro in the early 1930s.  MD 202 was relocated through Landover in the early 1940s.  The highway was expanded to a divided highway with several interchanges from Bladensburg through Landover and Largo from the early 1960s to the mid-1970s.  In the 1990s, MD 202's divided highway segment was extended halfway to Upper Marlboro and expanded again through Largo, including the construction of several auxiliary routes to connect the highway with FedExField. Maryland Route 408 (MD 408) is a state highway in the U.S. state of Maryland.  Known as Mount Zion-Marlboro Road, the highway runs 5.62 mi from MD 4 at Waysons Corner east to MD 2 and MD 422 in Lothian.  MD 408 is the old alignment of MD 4 in southern Anne Arundel County.  The highway was constructed in the late 1910s and became the easternmost part of MD 4 in 1927.  The highway received its present designation in the mid-1960s when MD 4 was rerouted south into Calvert County.  MD 408's western end was relocated when MD 4 was upgraded to a freeway through Waysons Corner in the early 1990s.  MD 408 was also applied to the old sections of MD 4 between Andrews Air Force Base and Upper Marlboro in Prince George's County.  The number was assigned after the MD 4 freeway was completed in the mid-1960s.  The Prince George's County portions of MD 408 were transferred to county maintenance in the late 1970s except the section through Upper Marlboro, which became MD 725. Maryland Route 262 (MD 262) is a state highway in the U.S. state of Maryland.  Known as Lower Marlboro Road, the route runs 4.26 mi from Chaneyville Road in Lower Marlboro east to MD 4 in Sunderland.  MD 262 was constructed in the late 1920s.

A north wing was added before 1844.  Content is one of the oldest buildings remaining in the county seat of Upper Marlboro, along with Kingston and the Buck (James Waldrop) House.  Content has always been owned by prominent families in the civic, economic, and social affairs of town, county, and state including the Magruder, Beanes, and Lee families; and the Bowling and Smith families of the 20th century. All Saints' Church is a historic Episcopal church located at 100 Lower Marlboro Road (near the intersection of Southern Maryland Boulevard MD 4 and Solomons Island Road MD 2), in Sunderland, Calvert County, Maryland.  All Saint's Parish was one of the thirty original Anglican parishes created in 1692 to encompass the Province of Maryland.  In 1693 its first parish church, a log structure, was built on an acre of land called "Kemp's Desire" donated by Thomas Hillary.  This log church was expanded in 1703-1704 and repaired at least 4 times before being replaced on top of the hill between MD routes 4, 262, and 2 by the present brick building.
