The title "Baron of Carnock" passed to another cousin Major General Sir William Nicolson, who was an only son of George Nicolson of Tarviston. The general saw service in the Americas, India, Ireland and Mauritius. He died in 1820 to be succeeded by his son, Admiral Sir Frederick Nicolson. In 1879, the admiral's eldest son, Frederick, was killed fighting the Zulus, so the title was passed to the second son, Arthur, in 1899. In June 1916 Arthur was created Baron Carnock of Carnock.
