Document 5: Four room house: A four room house, also known as an "Israelite house" or a "pillared house" is the name given to the mud and stone houses characteristic of the Iron Age of Levant. Although sometimes considered particularly Israelite, they are also found in non-Israelite sites.(A. Mazar, 1985a: 67-8; Finkclstein, 1988: 237-59)." Their origins are uncertain. The house's inhabitants lived on the second floor, the ground floor being used as a stable for livestock, and for storage. The four room house is so named because its floor plan, divided into four sections; it is also sometimes called a pillared house because three ground-level "rooms" are separated by two rows of wood pillars holding up the second floor. The pillars, however, are not the defining feature of the four roomed house, and this error of terminology leads to the confusion of four roomed houses with other buildings such as storehouses and stables, where pillars were widely used, but which were not constructed under the four room house layout.
Document 6: Croco House: The Keifer Croco farm was a stop along the Underground Railroad. This was a parallel route to Wooster east of the route through modern Shreve. Along with the John Croco farm, next door, served as waystations and hiding places for slaves moving northward, prior to the American Civil War. From here, the escapee would be transported to Thomas Smiths farm. Smith would then forward them to Isaac Daniel directly or via Daniel Clark in Apple Creek. The attic was designed to hide escaping slaves. A trap door was hidden in the ceiling provided access. The John Croco barn, a half-mile away had a cellar, where runaways could be sheltered. Bill and Rosanna Painter purchased and restored the Croco house around 2001.(pg 105)
Document 7: Louis DeSaussure House: The Louis DeSaussure House is an antebellum house at 1 East Battery, Charleston, South Carolina. The house was designed and built for Louis DeSaussure by William Jones and completed in late 1859.

In 1865 during the Civil War, the house was damaged when evacuating Confederate forces blew up a large cannon at the corner of East Battery and South Battery; a piece of the cannon was lodged in the attic of the house. The balconies on the East Battery façade and window ornaments were installed when the house was restored after the earthquake of 1886 by Bernard O'Neill, who bought it in 1888. The house was used by the military to house Navy officers during World War II and was later converted into apartments. The carriage house for 1 East Battery was later subdivided into a separate house known as 2 South Battery.

Alternate names include "shotgun shack", "shotgun hut", "shotgun cottage", and in the case of a multihome dwelling, "shotgun apartment". A railroad apartment is somewhat similar, but instead of each room opening onto the next room, it has a side hallway from which rooms are entered (similar to compartments in passenger rail cars).
Document 9: Robinson House (Manassas, Virginia): Robinson House sits at the bottom of Henry Hill, near Bull Run in Virginia.

The National Park Service acquired this parcel as part of their effort to commemorate two major battles of the American Civil War, the First and Second battles of Bull Run (also known as First and Second Manassas) which occurred about one year apart. Both battles were Confederate victories. However, Robinson House managed to survive virtually unscathed.

In the 1920s, U.S. Route 66 was routed through the district, increasing traffic for local businesses. Sayre's Classical Revival post office, a contributing property, was constructed in 1938; the post office includes a Works Progress Administration mural painted in 1940. The downtown remained prosperous until the 1950s, when population decline and the bypassing of Route 66 led to a decrease in commercial activity.

Document 14: Mississippi Delta: The Mississippi Delta is the distinctive northwest section of the U.S. state of Mississippi which lies between the Mississippi and Yazoo Rivers. The region has been called "The Most Southern Place on Earth" ("Southern" in the sense of "characteristic of its region, the American South"), because of its unique racial, cultural, and economic history. It is 200 miles long and 87 miles across at its widest point, encompassing circa 4,415,000 acres, or, some 7,000 square miles of alluvial floodplain. Originally covered in hardwood forest across the bottomlands, it was developed as one of the richest cotton-growing areas in the nation before the American Civil War (1861-1865). The region attracted many speculators who developed land along the riverfronts for cotton plantations; they became wealthy planters dependent on the labor of black slaves, who comprised the vast majority of the population in these counties well before the Civil War, often twice the number of whites.
Document 15: Kingstree Historic District: The Kingstree Historic District contains forty-eight properties situated along Main Street, Academy Street, and Hampton Street in the commercial area of downtown Kingstree, South Carolina. The district includes the courthouse, public library, railroad station, and numerous commercial buildings. The district is a fine collection of nineteenth-century vernacular commercial architecture. Details such as arched doorways and windows, cast-iron columns and pilasters, decorative or corbelled brickwork and pressed tin interior ceilings are present on most of the district’s buildings. The Williamsburg County Courthouse, built ca. 1823, and designed by Robert Mills, is a fine example of Roman neoclassical design with its raised first floor, pediment with lunette, and Doric columns. In 1953-54 the courthouse underwent substantial remodeling on the exterior and interior, though it still reflects much of Mill’s original design. With the exception of the courthouse, most of the buildings in the district were built between 1900 and 1920 when Kingstree enjoyed prosperity as a retail and tobacco marketing center of Williamsburg County. The majority of the buildings in the district are a visible record of this twenty-year growth and the historic fabric of the area remains substantially intact. The Kingstree Historic District was listed in the National Register of Historic Places June 28, 1982.
