It is a two-story, five-bay log dwelling resting on low fieldstone foundations, with a one-story, three-bay stone addition. Numerous sheds and outbuildings are located near the house. The house was built by George Adam Geeting [1741-1812], who settled on this land near Little Antietam Creek after immigrating to the English Colony of Maryland in 1759 from his native Prussia. Geeting farmed his land and taught in a log schoolhouse nearby which became a regular preaching appointment for services held by Rev. Philip William Otterbein, one of the founding leaders of the United Brethren in Christ, the first denomination organized in the United States of America. In the mid-1770s, Geeting erected a meetinghouse which later became known as Mount Hebron Church, the first structure built expressly for services of the future United Brethren in Christ denomination. Salem United Methodist Church in Keedysville is the successor to the Mount Hebron Church and Geeting Meetinghouse. Getting himself was ordained a minister of the German Reformed Church in 1788 and traveled extensively through Western Maryland, Virginia, and Pennsylvania as an itinerant preacher. On September 25, 1800, George Adam Geeting attended the first conference of the United Brethren in Christ at the home of Peter Kemp near Frederick, Maryland. It was at this conference that the United Brethren in Christ was formally organized as a denomination and took its name. Geeting continued serving as a minister for the new church, acted as secretary of the denominational conference, and served as a bishop of the United Brethren in Christ briefly in 1812 before his death.

East Nottingham Meetinghouse, or Brick Meetinghouse, is a historic Friends meeting house located at Rising Sun, Cecil County, Maryland. It consists of three different sections: the Flemish bond brick section is the oldest, having been built in 1724, 30 feet 3 inches (9.22 m) by 40 feet 2 inches (12.24 m); the stone addition containing two one-story meeting rooms on the ground floor, each with a corner fireplace at the south corners of the building, and a large youth gallery on the second floor; and in the mid 19th century, a one-story gable roofed structure was added at the southwest corner of the stone section to serve as a women's cloakroom and privy. It is of significance because of its association with William Penn who granted the site "for a Meeting House and Burial Yard, Forever" near the center of the 18,000-acre (73 km2) Nottingham Lots settlement and was at one time the largest Friends meeting house south of Philadelphia. The Philadelphia Half-Yearly Meeting was held here as early as 1725. During the Revolutionary War, an American Army hospital was established here in 1778 for sick and wounded troops under General William Smallwood's command and the Marquis de Lafayette's troops camped in the Meeting House woods on the first night of their march from the Head of Elk to victory at the Battle of Yorktown in 1781.

Keedysville Historic District is a national historic district at Keedysville, Washington County, Maryland, United States. The district boundary is within the corporate limits of the town, generally focused on the properties lining Main Street and those associated with the now-abandoned railroad facilities. It is reflective of the town's growth from the 1768 establishment of Jacob Hess' mill along the old Conococheague migration road to expansion with each new transportation development. The first major development was the Boonsboro-Sharpsburg turnpike. With the advent of the Baltimore and Ohio Railroad through the center of town, shops and manufactures were established and expanded. The town's prosperity waned with the loss of railroad service in 1953. The district is also significant for the wide range of architectural stylistic influences present on the buildings through the historic town.
