Hopewell is a rural community located along the West Branch of the East River. It was named after the ship that brought Alexander McNutt and the Ulster settlers to Colchester County in 1761. An early name for the area was Milltown from the John Duffs grist mill.
Millbrook is a rural community located south of the Trans-Canada Highway, west of Rocklin. Originally, some of the early settlers visited the area, and trapped a large bear, they then named the place Bear Brook. Donald McKenzie built a mill sometime between 1803 and 1809 which prompted the renaming of Bear Brook to Millbrook.
