Borland or Bordland also meant the land that was granted to the feudal superior specifically to be used to furnish food for his castle or dwelling. There has been a modern-day military use of Dunlop Hill, for in the 20th-century, between the two World Wars, a Royal Observer Corps post composed of huts was built on top of the hill. The personnel tracked enemy-aircraft movement up the Clyde towards Glasgow. Development of more sophisticated radar tracking techniques after World War II made the facility redundant. Until the 1970s the UK Warning and Monitoring organisation operated a bunker on the hill top. The access door and ventilation louvres are still in place. The Dunlops of that Ilk The first recorded Dunlop is William de Dunlop of 1260, followed by a supporter of Edward I, Neil Fitz-Robert de Dulap of 1306. His estates were forfeited due to his support for John Balliol, as were those of the De Rosses. The family regained their lands by the mid 15th.

Sir James Dunlop of that Ilk held the estate in 1596 and married Jean, daughter of Somerville of Cambusnethan, descended from Lord Somerville. This may go some way to explaining why the Somerville family came to purchase lands at Montgomery-Crivoch and Bollingshaw in the 1800s to establish the Kennox Estate.

John Dunlop 1748-1784 married the daughter of Sir Thomas Wallace of Craigie. She was the patron of Burns already referred to. John Dunlop Esq. MP was resident at Dunlop House in 1837 and Pigot describes it as one of Ayrshires' handsomest mansions, with the Ogrestone or Thurgatstane lying within its estate boundaries. The house was designed in 1831-34 by David Hamilton for Sir James Dunlop of Dunlop. The house is an unusual Scottish-Jacobean style, but the gate lodge is more typical of Hamilton, with strap work, classical and manorial features (Milligan). The last Baronet was Major Sir James Dunlop of 1839-1858 who died unmarried. The last of the Dunlops to be born at Dunlop were John (1904) and Alexander (1906) Houison Crawfurd.
