Context: John Wesley North (1815–1890) was a 19th-century pioneer American statesman of national reputation.  He was the founder of the cities of Northfield, Minnesota and Riverside, California, where John W. North High School and the John W. North Water Treatment Plant are located and named after him.  He also received a Presidential appointment to Nevada's highest court, the predecessor of the United States District Court for the District of Nevada. Renner is an extinct American village in Indiana's Blackford County.  Although Renner has been listed as a “populated place” by the U.S. Geological Survey, this description is misleading.  Renner was a railroad stop on the Pittsburgh, Cincinnati and St. Louis Railroad.  The land around the railroad stop was originally used to supply timber for railroad crossties, and eventually became a livestock farm.  Housing for the families of the employees of the livestock farm was also located nearby.  Although it is not known for certain, Renner is thought to have been named for railroad executive John W. Renner.  Renner was an executive of the Pittsburgh, Cincinnati and St. Louis Railroad, and later the Pennsylvania Railroad, and retired with over 50 years of railroad experience.  Another community, Rennerdale, Pennsylvania, was named in his honor in 1895. The John W. Pope Jr.  Convocation Center is a multi-purpose arena in Buies Creek, North Carolina.

Jones House currently stands at 1250 Davis Street, Elmira, New York, across from a historic entrance to Woodlawn Cemetery.  It is the former home of John W. Jones and current home of the John W. Jones Museum.  It stands on part of its original property, though it originally faced College Avenue.  Historically, the house was the private residence of John W. Jones and his family, but changed ownership several times since, and was used as rental property that fell into disrepair.  Condemned by the City of Elmira in 1997, Lucy Brown brought it to the public’s attention and with a group of concerned citizens, saved it from demolition.  It is now the home to the John W. Jones Museum. The John W. Coffren House and Store are two historic buildings located at Croom in Prince George's County, Maryland.  This assemblage is significant for their architecture, as well as their association with the commercial history of the area and with John W. Coffren, local merchant and landowner.  The Coffren House, built in 1861, has a Greek Revival entrance and interior detail.  The Coffren Store, constructed ca. 1853, is a utilitarian structure, designed for use as a one-room general store.  The store closed in 1945.  The significance of the house and store together is that they are an intact example of house and store complexes that served rural communities in the county during the 19th century.  Their builder, John W. Coffren (1828-1874), who rose from ditch digger to wealthy merchant, served on the Vestry of St. Thomas Church in Croom and on the Prince George's County School Board, as well as owning much of the property in the Village of Croom.
