T.B.
A 19th Century crossroads community named for a boundary stone with a “T” on the west side and “B” on the east to mark the division of acreage of William Townshend and Thomas Brooke. Established at the intersection of pre-revolutionary roads linking the port town of Accokeek with plantations on the Patuxent, Piscataway Village, and Upper Marlboro, T.B. became a commercial center and a stop on the stagecoach line to Washington. Bypassed by railroads through Brandywine in the 1880s, T.B. became a quiet rural village.
Marker is at the intersection of Branch Avenue (Maryland Route 5) and Accokeek Road (Maryland Route 373), in the median on Branch Avenue.
