A postal office operated in the community from 21 July 1864 to present with brief stops in service during the American Civil War. By 1878 the town expanded to three general stores and a wheelwright shop. One of which is Maloney's General Store built shortly after the civil war which served as a stagecoach stop and was later owned by Royal Harp III, Thomas Isaacs, Mr White, and the Grant Family.
The Dayton single room school house was along Green Bridge Road. After a fire in the single room schoolhouse for colored children, a new brown tile two room school was built at the crossroads of Ten Oaks, Green Bridge and Howard roads, and the colored children moved to the old white school. The two room school is now on property owned by RLO Contractors.
In 2014, a zoning case to move a large industrial mulching operation operated by a Sandy Spring Bank executive and RLO[clarification needed] president from Trinity Church in Elkridge to agricultural preservation land in Dayton prompted a large citizen reaction.
