From http://en.wikipedia.org/wiki/James_Hamilton,_1st_Duke_of_Abercorn Born at Seymour Place, Mayfair, Abercorn was the son of James Hamilton Viscount Hamilton, who died when his son was only three, eldest son of John Hamilton 1st Marquess of Abercorn. His mother was Harriet Douglas, second daughter of the Hon. John Douglas.
He was educated at Harrow School and Christ Church College, Oxford. In 1818 he succeeded his grandfather in his titles. He received a Honorary Doctorate of Civil Laws by the University of Oxford in 1856.
In 1844, Lord Abercorn was made a Knight of the Garter at the relatively young age of 33, becoming that same year Lord Lieutenant of Donegal. Two years later he was appointed a Privy Counsellor and Groom of the Stole to Prince Albert, and remained a prominent figure in the royal court for the next two decades.
In 1866, he was appointed Viceroy of Ireland, and two years later was created Marquess of Hamilton (in the Peerage of the United Kingdom) and Duke of Abercorn (in the Peerage of Ireland), resigning shortly after William Ewert Gladstone won the 1868 general election. He was reappointed to the post in 1874, and the Duke served as Viceroy until his resignation in 1876, partly on account of his wife’s ill health.

Abercorn was Envoy Extraordinary for the investiture of Umberto I of Italy with the Order of the Garter on 2 March 1878.
