The Baronetcy, of Killyleagh in the County of Down, was created in the Baronetage of Ireland in 1763 for Robert Blackwood, the father of Sir John Blackwood. He was the son of John Blackwood and Ursula Hamilton, the daughter and co-heir of Robert Hamilton of Killyleagh, County Down. The Blackwood family, originally of Scottish descent, were prominent landowners in County Down and controlled the borough constituency of Killyleagh in the Irish Parliament.
Lady Dufferin and Claneboye was succeeded by her son, the second Baron, who had already succeeded his father as third Baronet. He represented Killyleagh in the Irish House of Commons and Helston and Aldeburgh in the British House of Commons and was also an Irish Representative Peer from 1820 to 1836. He was childless and was succeeded by his younger brother, the third Baron.
The latter's grandson, the fifth Baron (pictured), was a prominent Liberal politician, diplomat and colonial administrator, and notably served as Governor General of Canada and Viceroy of India. In 1850, at the age of twenty-three, he was created Baron Clandeboye, of Clandeboye in the County of Down, in the Peerage of the United Kingdom, which gave him a seat in the House of Lords. In 1871 he was created Viscount Claneboye, of Claneboye in the County of Down, and Earl of Dufferin, in the County of Down, and in 1888 he was even further honoured when he was made Earl of Ava, in the Province of Burma, and Marquess of Dufferin and Ava, in the County of Down and in the Province of Burma. These titles were also in the Peerage of the United Kingdom. Lord Dufferin and Ava also assumed by Royal license the additional surname of Hamilton in 1862 and that of Temple (which was the maiden name of his father's mother) in 1872.
His eldest son and heir apparent Archibald James Leofric Temple Hamilton-Temple-Blackwood, Earl of Ava, was killed at the Siege of Ladysmith during the Second Boer War while serving as a war correspondent. He was unmarried and the Marquess was therefore succeeded by his second son, the second Marquess. On his death the titles passed to another brother, the third Marquess. He was a soldier and also served as Speaker of the Senate of Northern Ireland. Lord Dufferin and Ava died in an air crash and was succeeded by his son, the fourth Marquess. He notably held office as Under-Secretary of State for the Colonies in the government of Neville Chamberlain.
After his death in the Second World War the titles were inherited by his six-year old son, the fifth Marquess. He was a well-known patron of arts. He was childless and on his death in 1988 the marquessate, earldoms, viscountcy and barony of Clandeboye (created in 1850) became extinct. However, he was succeeded in the baronetcy and barony of Dufferin and Claneboye by his distant relative Sir Francis George Blackwood, 7th Baronet, of the Navy (see below), who became the tenth Baron. As of 2007 the titles are held by the latter's son, the eleventh Baron, who succeeded in 1991. Like his father he lives in Australia.
The Blackwood Baronetcy, of the Navy, was created in the Baronetage of the United Kingdom in 1814 for the Hon. Henry Blackwood, seventh son of Sir John Blackwood, 2nd Baronet and of Dorcas Blackwood, 1st Baroness Dufferin and Claneboye. He was a Vice-Admiral of the Blue in the Royal Navy and was the bearer of despatches announcing the victory of Trafalgar in 1805. As mentioned above his descendant the seventh Baronet succeeded as tenth Baron Dufferin and Claneboye and eleventh Baronet of Killyleagh in 1988.
As of 30 June 2006, the present holder of the barony has not successfully proven his succession to the baronetcy of 1763 and is therefore not on the Official Roll of the Baronetage, with the baronetcy considered dormant (for more information follow this link).
