James Albert Edward Hamilton, 3rd Duke of Abercorn, is born in Hamilton Place, Piccadilly, London, on November 30, 1869. Styled Marquess of Hamilton between 1885 and 1913, he is a British peer and Unionist politician. He serves as the first Governor of Northern Ireland, a post he holds between 1922 and 1945. He is a great-grandfather of Diana, Princess of Wales.
Hamilton is the eldest son of James Hamilton, 2nd Duke of Abercorn, and godson of the Prince of Wales. His mother, Lady Mary Anna, is the fourth daughter of Richard Curzon-Howe, 1st Earl Howe. He is educated at Eton College and subsequently serves first in the Royal Inniskilling Fusiliers until 1892 when he joins the 1st Life Guards. He is later transferred as major to the North Irish Horse.
In the 1900 general election, Hamilton stands successfully as Unionist candidate for Londonderry City, and three years later he becomes Treasurer of the Household, a post he holds until the fall of Arthur Balfour‘s Conservative administration in 1905. After serving for a time as an Opposition whip, Hamilton succeeds his father as third Duke of Abercorn in 1913. In 1922, he is appointed governor of the newly created Northern Ireland. He also serves as Lord Lieutenant of Tyrone from 1917 until his death, having previously been a Deputy Lieutenant for County Donegal. Abercorn proves a popular royal representative in Northern Ireland, and is reappointed to the post in 1928 after completing his first term of office. In 1931, he declines the offer of the governor generalship of Canada, and three years later he is again reappointed governor for a third term. He remains in this capacity until his resignation in July 1945.
Abercorn is made the last non-royal Knight of the Most Illustrious Order of Saint Patrick in 1922. In 1928 he becomes a Knight of the Most Noble Order of the Garter and is also the recipient of an honorary degree from the Queen’s University Belfast. He receives the Royal Victorian Chain in 1945, the same year he is sworn of the Privy Council.
Abercorn marries Lady Rosalind Cecilia Caroline Bingham, only daughter of Charles Bingham, 4th Earl of Lucan and his wife Lady Cecilia Catherine Gordon-Lennox at St. Paul’s Church, Knightsbridge, on November 1, 1894. They have three daughters and two sons.
