Mattaponi, also known as the John Bowie Jr. House, is a historic home in Croom, Maryland, built c. 1820 on the foundation of an earlier house dating to the 1730s, three miles northwest of Nottingham, Prince George's County, Maryland.John Bowie, Sr., who emigrated to colonial Maryland in 1705 from Scotland, purchased a large tract of land called "Brooke's Reserve" about two miles west of Nottingham for a son, Captain William Bowie, when the son was twenty-one years old. A large brick house was erected there that was called Mattaponi, the name of the nearest creek and a Native American word meaning "meeting of the waters". The tract of land later became known by the name for the house. The current house is the second, being built on the foundation of the first. A tribe by the name Mattaponi resided in what would become colonial Virginia. The Bowie family had extensive landholdings in the county and were important politically. They settled in and near Nottingham during the colonial period, building a number of homes including Mattaponi.Robert Bowie, Governor of Maryland from 1803 to 1806 and 1811–12, is buried at Mattaponi and is believed to have been born there as well, although this is not proven; as an adult, he made his residence at "The Cedars" in Nottingham on the Patuxent River. Mattaponi is very similar in styling to the home he built nearby for his daughter, Bowieville, also brick covered with stucco.Walter Bowie also was born at Mattaponi.In December 1846, Richard Lowndes Ogle married Priscilla Mackall Bowie at Mattaponi.

The Nanjemoy Formation is a geologic formation pertaining to both the Wilcox Group and the Pamunkey Group of the eastern United States, stretching across the states of Virginia, Maryland, and District of Columbia. The formation crops out east of the Appalachians and dates back to the Paleogene period. Specifically to the Ypresian stage of the Eocene epoch, about 55 to 50 Ma or Wasatchian in the NALMA classification, defined by the contemporaneous Wasatch Formation of the Pacific US coast. The about 20 metres (66 ft) thin formation crops out in a narrow irregular band and only in certain of the many creeks of the Maryland peninsula and on the southern side of the Potomac River in Virginia. The two members the formation was divided into by Clark and Martin in 1901; Potapaco and Woodstock, represent different phases in the basin history. The lower Potapaco Member is much more clayey, described as marl, than the upper Woodstock Member, probably characteristic of less storm influences in the shallow shelf sediments. The formation has provided a wealth of fossils of mainly fish, but also mammals, reptiles, birds and flora. The presence of the sharks Otodus obliquus and Carcharocles aksuaticus, as well as various other shark and ray species are notable. Crocodylian, snake, turtle, mammal, and bird remains have all been found in the Nanjemoy Formation.

Bristol is an unincorporated community in Anne Arundel County, Maryland, United States. Jug Bay Wetlands Sanctuary (a stop on the Patuxent Water Trail) and the colonial town of Pig Point (alternately referred to as Bristol Landing and Leon at times) are on the Patuxent River waterfront portion of Bristol.

In the mid-twentieth century, the segregated Bristol Elementary School was located in the northern part of town, three-quarter mile southeast of Waysons Corner and a half mile south of the crossroad village of Drury. The school in 1953 published a history of Bristol (largely reprinting a 1927 Bristol town history from the Annapolis Capital newspaper). The following year it was enlarged and renovated, growing to 200 students (and four teachers and a heating and rodent problem) by 1969 after the county was ordered to desegregate schools in 1966.

The John W. Coffren House and Store are two historic buildings located at Croom in Prince George's County, Maryland.

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.The complex was listed on the National Register of Historic Places in 1987.
