Frederick Temple Hamilton-Temple-Blackwood, 1st Marquess of Dufferin and Ava.
the fifth Baron, 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 Clandeboye, of Clandeboye 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.
