Lord Breadalbane and Holland's elder son Duncan Campbell, styled Lord Ormelie, was overlooked for the succession (owing to his "incapacity") and died childless in 1727. Breadalbane nominated his younger son
John as his successor, as allowed by the patent, and this John consequently succeeded in the titles on his father's death in 1717.
John Campbell, 2nd Earl of Breadalbane and Holland sat in the
House of Lords as a
Scottish representative peer between 1736 and 1747. He was succeeded by his son, also John, the third Earl. The
third Earl was a prominent statesman, ambassador and a Lord of the Admiralty. He married as his first wife Lady Amabel Grey, daughter of
Henry Grey, 1st Duke of Kent. Their daughter
Lady Jemima Campbell succeeded her maternal grandfather as Marchioness Grey in 1740. Through Lady Jemima this Lord Breadalbane was a great-grandfather of Prime Minister
Lord Goderich. The third Lord Breadalbane outlived both his only son by his first wife and his two sons by his second marriage to Arabella Pershall. On his death in 1782 the male line of the first Earl failed. The late third Earl was succeeded by his kinsman, the great-grandson of Colin Campbell of Mochaster, younger son of Sir Robert Campbell, 3rd Baronet, and uncle of the first Earl.
John Campbell, who became the fourth Earl. He was a
Lieutenant-General in the
British Army and sat in the
House of Lords as a
Scottish representative peer between 1784 and 1806. In 1806 he was created
Baron Breadalbane, of Taymouth Castle in the County of Perth, in the
Peerage of the United Kingdom, which entitled him to an automatic permanent seat in the House of Lords. In 1831 he was further honoured when he was made
Earl of Ormelie and
Marquess of Breadalbane in the Peerage of the United Kingdom. He was succeeded by his only son, John Campbell, who became the
second Marquess.
John Campbell, 2nd Marquess of Breadalbane was a
Liberal politician and served twice as
Lord Chamberlain of the Household. He was childless and the United Kingdom peerages of Baron Breadalbane, Earl of Ormelie and Marquess of Breadalbane became extinct on his death in 1862. He was succeeded in the Scottish titles by his kinsman, John Campbell, who became the sixth Earl. The sixth Earl was the grandson of James Campbell, great-great-grandson of William Campbell of Glenfalloch (died 1648) who was in turn the brother of the aforementioned Colin Campbell of Mochaster. On his death the titles passed to his son, Gavin, the
seventh Earl. He was a Liberal politician and notably served as
Treasurer of the Household and
Lord Steward of the Household. In 1873 he was created
Baron Breadalbane, of Kenmure in the County of Perth, in the Peerage of the United Kingdom, which entitled him to an automatic seat in the House of Lords. In 1885 he was made
Earl of Ormelie, in the County of Caithness, and
Marquess of Breadalbane in the Peerage of the United Kingdom, thus recreating the UK peerage titles held by the third Earl. Gavin Campbell was however childless and these titles consequently again became extinct on his death in 1922. He was succeeded in the Scottish titles by his nephew, Iain Campbell, the eighth Earl. Iain was the son of Captain the Honourable Ivan Campbell, second son of the sixth Earl. Iain, the eighth Earl, died at an early age in 1923, only a year after succeeding his uncle. Iain was succeeded by his kinsman, Charles Campbell, the ninth Earl. Charles was the son of
Major-General Charles William Campbell of Borland, grandson of John Campbell of Borland, younger brother of the aforementioned James Campbell, grandfather of the sixth Earl.
Charles Campbell, 9th Earl of Breadalbane and Holland sat in the House of Lords as a Scottish Representative Peer between 1924 and his death in 1959. He was succeeded by his only son, John, the tenth Earl. John was severely wounded while serving with the
Black Watch in the
Second World War and he died childless in 1995 when the titles became dormant. ==Pretenders==
