The Tredegars were an important family, who may also have had links to the nearby Wilmington Manor. During the Tredegars' ownership of the heath, and probably between the dates 1820 -1874, the heath was extensively exploited. Minet posthumously won his case, which is in large part responsible for the preservation of the remaining heath to this day, though large parts were later destroyed for road building: in 1926, for construction of the first Dartford by-pass (Princes Road), and 1970, for the cutting of Rochester Way (the present A2). Ironically, it was Tredegar who was commemorated when a new road at Leyton Cross was named after him in the 20th century. After the death of Charles in 1874, the Minet family appears to have been left with financial difficulties; between 1874 and 1882 much of Baldwyns Park was sold off in lots. One sale advertisement read:The beautiful Freehold Residential Estate, distinguished as Baldwyns, extending over about 841 acres in the parishes of Dartford, Wilmington and Bexley, a short distance only from the ancient and interesting market town of Dartford, about a mile away from Bexley and Crayford and only 14 by road from London, in a neighbourhood proverbially healthy and picturesque, and with excellent railway facilities by the North Kent Line, by which the City and West End are reached in little more than half an hour. It comprises a capital Mansion, with suitable attached and detached offices of every description, desirable for the occupation of a family of distinction, approached by a carriage drive, with ornamental entrance lodges, beautiful pleasure grounds, gardens, and orchards, surrounded by a richly timbered park, ornamental woods, plantations, and adjacent meadow land, through which are delightful walks of considerable extent. And immediately adjoining is the farm known as Stonehill, farm buildings, and numerous enclosures of productive land, also several cottages for labourers. The woodland, which includes the well known Ruxley-Heath, Rowhill and Joydens Woods, is well adapted for the rearing of preservation game, and affords excellent shooting, and several packs of hounds hunt the district. The property presents unusual attractions as the site of the ancient city of Caswallon, and from the interesting remains of encampments and excavations made by our Celtic ancestors found thereon; while in addition to its present residential advantages, it possesses extensive frontages of Dartford Heath and the high road, immediately available for building purposes, and by a judicious widening of the intersecting road leading from Bexley to Wilmington.Dartford Express, 25 July 1874 Clayton Croft and the Maypole area were sold by auction in 1882.
