FatherArchibald Rowan HAMILTON (1818-1860)
Individual Notes
• After several generations of Dufferins, in 1862 the eldest son married Harriet Rowan-Hamilton, the eldest daughter of the Castle, and the two families were reunited. The husband was created 1st Marquess of Dufferin and Ava and the family seat is still Clandeboye which had come to the original Miss Hamilton of the gatehouse when the Hamilton estates were equally divided. [6900, p 10]

• His wife was the eldest daughter of the late Archibald Rowan Hamilton, of Killyleagh Castle, co. Down, and sister of the present owner of that historic seat, Colonel Gawen William Rowan Hamilton. [6908], [6887]

• Lady Dufferin was very active during her husband’s term as Governor General. She was the first spouse to accompany the Governor General on a tour, visiting southern Ontario in 1872. [6912, p 2]

• Throughout the Dufferin’s term of office, Lady Dufferin wrote weekly letters to her mother back in Ireland. [6912, p 2]

• When Governor General of Canada, the Marquess of Dufferin and his wife Harriet Hamilton visited Chatham, when I don’t know, but they went by our old house at 157 Park St. in a motorcade, and Grandmother Read said “Harriet was her cousin.”
I firmly believe this to be true, as there is too many consistencies to our family history which are parallel to the Killyleagh Castle Hamiltons.
