Froggy Hollow took its name from the large and loud frog population around Little Bennett Creek. Before Kingsley School was built, white children living nearby attended neighboring community schools and had to walk long distances through the back woods because there was no bus transportation, while local African American children attended classes at the old Hyattstown Christian Church because Montgomery County's public facilities remained segregated by race until 1961. After concerned parents appealed for a local school, Kingsley School opened here in September 1893 and was named for the King family, a prominent local family. It remained open until 1935, when low enrollment during the Great Depression forced its closure. The one-room schoolhouse was plainly equipped with a slate chalkboard, simple wooden desks, a globe, a Victrola record player, a wood-burning stove, separate outhouses for boys and girls, and a playground with swings and seesaws behind the building; when weather allowed, children played baseball, softball, dodge ball, and also fished, ice skated, and sledded. Built with State of Maryland funds sufficient only for basic materials, the building later passed into private hands until Montgomery Parks acquired the property in 1964. Beginning in 2008, renovations drew on interviews, photographs, and archival documents to return the schoolhouse to its 1920s appearance, including replacing deteriorated windows and exterior framing, reconstructing cloakrooms, installing a new wood floor, repairing the slate chalkboard, and repainting it in historically accurate colors.
