, estate inherited by Lansdowne A great-grandson of British Prime Minister
Lord Shelburne (later 1st
Marquess of Lansdowne) and the eldest son of
Henry Petty-Fitzmaurice, 4th Marquess of Lansdowne, and his wife,
Emily, 8th Lady Nairne (
née de Flahaut), Henry Charles Keith Petty-Fitzmaurice was born in 1845 at
Lansdowne House, their family seat in London. His maternal grandfather, Count
Charles de Flahaut, was an important French general to
Napoleon Bonaparte, and a member of his family. He fought along his side during many battles and later occupied the functions of Ambassador and Senator of the Empire. Through his mother
Emily, Lansdowne was half-nephew of Emperor
Napoleon III, a step-grandson of Queen
Hortense Bonaparte, and a great-grandson of Prince
Talleyrand, the Emperor's foreign minister. His maternal great-grandfather,
George Elphinstone, 1st Viscount Keith, was also the Admiral who prevented
Napoleon's escape from France after the
Battle of Waterloo, and who received and supervised his final exile to
St. Helena in 1815. Lord Lansdowne was a member of the
Fitzmaurice/
Petty-Fitzmaurice family, a cadet branch of the
House of FitzGerald of Ireland. He held the
courtesy title Viscount Clanmaurice from birth to 1863 and then the courtesy title
Earl of Kerry until he succeeded as
Marquess of Lansdowne in 1866. Upon his mother's death in 1895, he succeeded her as the
9th Lord Nairne in the
Peerage of Scotland. He was estimated to be the sixteenth richest peer in the United Kingdom, and the fourth largest landowner. At one of his inherited properties,
Derreen House (Lauragh,
County Kerry, in the present-day
Republic of Ireland), Lord Lansdowne started to develop a great garden from 1871 onwards. For most of the rest of his life, he spent three months of the year at Derreen. Lord Lansdowne entered the
House of Lords as a member of the
Liberal Party in 1866. He served in
William Ewart Gladstone's government as a
Lord of the Treasury from 1869 to 1872 and as
Under-Secretary of State for War from 1872 to 1874. He was appointed
Under-Secretary of State for India in 1880 and, having gained experience in overseas administration, was appointed
Governor General of Canada in 1883, replacing
John Campbell, 9th Duke of Argyll, the son-in-law of
Queen Victoria. His great-grandfather,
Lord Shelburne, had previously founded
Boodle's Club, which had as members
Adam Smith, the
Duke of Wellington, Sir
Winston Churchill, and
Ian Fleming, among others, and is now the second oldest club in the world. In 1897, he also became a founding trustee of the
National Gallery of British Art, with the
Earl of Carlisle of
Castle Howard,
Lord Brownlow of
Belton House,
Alfred de Rothschild of
Halton House, Sir
Charles Tennant of
Glen House,
John Postle Heseltine of
Walhampton House, and Sir John Murray Scott. ==Governor General of Canada, 1883–1888==
