 After the Admiral's death in March 1867, the estate passed to his son, George Arthur Ferguson, the sixth and final laird. He served in the Grenadier Guards and eventually became a captain. He married Nina Maria Hood, the eldest daughter of Alexander Nelson Hood, 1st Viscount Bridport, in February 1861. Later that year Captain Ferguson was posted to Canada, where he was promoted to Lieutenant Colonel and where his first two sons, Arthur and Francis William, were born. His eldest son, Arthur, became Inspector of Constabulary for Scotland. Returning to Britain in 1864, the family had a nomadic lifestyle, but the sixth laird and his wife were extravagant and habitual gamblers. In June 1909, a trust deed was registered, and what remained of the estate was put on the market. After large parts of the land had been sold under the ownership of the sixth laird the estate was listed by Bateman in 1883 as being just over 23,000 acres (93 square kilometres) with an income of £ 19,938; at the height of its development the estate had occupied 50 square miles (130 square kilometres), and was valued at £ 30 million.
