Since 1962, children in Wampum proper and Chewton have attend Ellwood City Area School District, considered the legal successor to Wampum Public Schools due to state-mandated school consolidation in the 1960s. Due to a dispute with the former Big Beaver Township School District that had an informal union with Wampum Public Schools but never merged with Wampum, children in New Beaver have attended Big Beaver's successor Mohawk Area School District since Ellwood City absorbed Wampum Public Schools.

Maryland Route 236 is a state highway in the U. S. state of Maryland. Known as Thompson Corner Road, the state highway runs 6.19 miles from MD 234 in Budds Creek north to MD 5 in Charlotte Hall. MD 236 parallels the western edge of St. Mary's County, connecting Charlotte Hall with U. S. Route 301 via MD 234; the state highway was constructed in the early 1930s. MD 236 begins at an intersection with MD 234 in the hamlet of Budds Creek, the site of a trio of racing facilities: Maryland International Raceway, Budds Creek Motocross, Potomac Speedway; the state highway intersects the old alignment of MD 234, Stone Corner Lane, heads northeast as a two-lane undivided road through farmland. The road passes several farms and homes that belong to the Amish community that lives in St. Mary's County. MD 236 intersects Lockes Crossing Road in the hamlet of Thompson Corner; the state highway continues north to Charlotte Hall, where the highway crosses the Three Notch Trail at grade and meets New Market Village Road.

New Market Village Road to the north, the old alignment of MD 236 and is unsigned MD 236A, heads through the hamlet of Newmarket toward the Charlotte Hall Historic District. MD 236 curves to the east to its northern terminus at MD 5, which intersects the highway at two separate intersections separated by a wide median containing businesses. MD 236 was constructed as a gravel road starting in 1929 from the north end. By 1930, a small segment of the highway was completed south from Charlotte Hall. MD 236 was completed in 1933 from Budds Creek to Charlotte Hall, albeit with a county-maintained gap between Wainwright Road and Ryceville Road toward the Budds Creek end; the portion of Thompsons Corner Road in the county system was transferred to the state highway system in 1956. MD 236 continued north along what is now MD 236A to its northern terminus at an acute intersection with MD 5 just south of the MD 5–MD 6 intersection in Charlotte Hall; when MD 5 was expanded to a divided highway through Charlotte Hall in 1962, MD 236 remained accessible only from southbound MD 5.

The northern end of MD 236 was relocated to its present perpendicular intersections with the opposing directions of MD 5 between 1981 and 1993. The entire route is in St. Mary's County. MD 236A is the designation for New Market Village Road, a 0.18-mile section of old alignment of MD 236 north through the village of Newmarket to an intersection with southbound MD 5 just south of MD 5's intersection with MD 6.
