Note 12 — THE CASTLES AND HALLS OF DURHAM By Henry R. Leighton

Some years before 1834, when Mackenzie wrote, a portion of it had been "converted into a respectable and substantial house," and was then the residence of Mr. Henry Morton, Lord Durham’s agent. In or about 1875 the house underwent further changes, and has now for many years been known as Lambton Grange. There is, however, another building in the Park, locally known as the old Hall, and at one time used as a brewery, which may represent some intermediate residence.
