Question: In which county in Delaware can one find a historic district that includes a number of homes where the rooms are arranged one behind the other with doors at each end?
Context: Millington Hall is a historic Grade II listed building in Cheadle Hulme, Stockport, England, that was constructed in 1683 and was part of the Lane End hamlet.  The building is located on Station Road adjacent to the local Methodist Church.  The family the hazeldine 's own the area after buying it from john millington were they had many businesses that involved building and carpentry, and had two saw mills one behind and one behind the old police station,there also opened the building as a restaurant in the 1960s before the building was converted and reopened in July 2004 as a public house called the "John Millington". Muggiaea is a genus of siphonophores in the family Diphyidae.  Members of this family are colonial siphonophores with two nectophores (swimming bells) arranged one behind the other, but in the genus "Muggiaea", the posterior nectophore is absent.  The anterior one has a complete dorsal ridge.  The somatocyst (extension of the gastrovascular system) is very close to the nectosac (central cavity with muscular walls) wall. Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque.  Examples include some aircraft propellers, resulting in the maximum power of a single piston or turboprop engine to drive two propellers in opposite rotation.  Contra-rotating propellers are also common in some marine transmission systems, in particular for large speed boats with planing hulls.  Two propellers are arranged one behind the other, and power is transferred from the engine via planetary gear transmission.  The configuration can also be used in helicopter designs termed coaxial rotors, where similar issues and principles of torque apply. The St. Louis Street Historic District is a residential historic district located along several blocks of St. Louis Street in Edwardsville, Illinois.  The district includes 59 homes, of which 51 are considered contributing to the district's historic character.  St. Louis Street was one of the most prestigious sections of Edwardsville in the late 1800s, and several of the city's wealthiest residents owned homes along the street.  The first house on the street, a log cabin, was built by John Lusk in 1809.  In the 1870s, prominent residents of Edwardsville began building homes on the south side of St. Louis Street; these houses typically had large plots and open parkland between lots.  In 1883, Judge Joseph Gillespie divided and sold the land on the north side of the street; the homes built on these lots are consequently much closer together.  The homes built in the district were designed in popular architectural styles of the late 1800s; while the Queen Anne style is the most prevalent, Italianate, Chateauesque, and Classical Revival houses were also built. Center City Historic District is a grouping of 19 homes and one church along Summit Avenue in Center City, Minnesota, United States.  It was listed as a historic district on the National Register of Historic Places in 1980.  Center City became the county seat of Chisago County in the 1870s, during a time of Swedish migration and settlement in the county.  The buildings in the historic district include the Chisago Lake Evangelical Lutheran Church, which was the main Swedish Lutheran parish in the area, as well as a number of residences built between 1888 and 1910.  The homes have moderate ornamentation and attention to architectural styling details of their period. A "shotgun house" is a narrow rectangular domestic residence, usually no more than about 12 feet (3.5 m) wide, with rooms arranged one behind the other and doors at each end of the house.  It was the most popular style of house in the Southern United States from the end of the American Civil War (1861–65) through the 1920s.  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). The Lower Arroyo Seco Historic District is a residential historic district in Pasadena, California.  The historic district encompasses homes located near the lower Arroyo Seco along Arroyo Boulevard, California Boulevard, La Loma Road, and Grand Avenue.  The district includes 78 contributing homes, the majority of which were influenced by the Arts and Crafts movement.  During the early twentieth century, when most of the homes in the district were constructed, Pasadena was one of three prominent centers of American Craftsman design, along with Chicago and the San Francisco Bay Area.  The district includes a variety of Craftsman designs only matched by one other area in California, a hilly neighborhood in Berkeley.  Several prominent architects, including Charles K. Sumner and Henry Mather Greene, designed homes in the district.  The Batchelder House, home of tile designer Ernest Batchelder, is included in the district. The Diphyidae are a family of siphonophores.  These are colonial siphonophores with two nectophores (swimming bells) arranged one behind the other.  The front one includes a somatocyst (extension of the gastrovascular system), while the hind one does not.  The somatocyst often contains an oil droplet for buoyancy control.  A nectosac (central cavity with muscular walls) in each nectophore allows the organism to swim efficiently. Bridgeville Historic District, also known as Lewisville and Lewis' Wharf, is a national historic district located at Bridgeville, Sussex County, Delaware.  The district includes 166 contributing buildings and 70 contributing structures at Bridgeville, a center of agricultural commerce.  The district is primarily residential with resources built from the second quarter of the 19th century through the Great Depression.  The dwellings are in a variety of vernacular forms including the "I-house," Shotgun house, and late 19th and 20th century revivals.  Located in the district and separately listed are the Bridgeville Public Library and Old Bridgeville Fire House. Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive two coaxial propellers in contra-rotation (rotation about the same axis in opposite directions).  Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission.  Contra-rotating propellers should not be confused with counter-rotating propellers—airscrews on separate shafts turning in opposite directions.
