Major-General Ivor John Caradoc Herbert, 1st Baron Treowen CB, CMG, KStJ (15 July 1851 – 18 October 1933), known as Sir Ivor Herbert, Bt, between 1907 and 1917, was a British Liberal politician and British Army officer in the Grenadier Guards,[1] who served as General Officer Commanding the Militia of Canada from 1890 to 1895. He was made a baronet in 1907 and raised to a barony in 1917.


Herbert was born at the family seat Llanarth Court, at Llanarth, Monmouthshire between Abergavenny and Raglan in Monmouthshire, the eldest son of John Arthur Edward Herbert, formerly Arthur Jones, of Llanarth (1818–1895).[2] In 1846 Ivor's father married Augusta Hall, the only surviving child and heir of Benjamin Hall, 1st Baron Llanover (1802–1867).[3] The marriage took place on 12 November 1846[4] and two years later, the father and his brothers assumed the name of Herbert by Royal License as the senior branch of the Herbert family.[5] (Ironically, no member of this family had been known by that name, so the Jones family was actually taking the name of a junior and more well-known branch, the Herbert earls of Powis descended from an ancient Welsh Catholic family).[6] His mother was the Honourable Augusta Charlotte Elizabeth Hall, the only surviving daughter and sole heiress of Benjamin Hall, 1st Baron Llanover and his wife Augusta Waddington, better known as the Welsh cultural nationalist Lady Llanover, heiress of the considerable Llanover estate in Monmouthshire.[7][8] He had two younger brothers, Edward Bleiddyn[9] and Arthur (whose descendants still own Llanover today).[10]

Political career

Herbert was Member of Parliament (MP) for South Monmouthshire from 1906 until 1917.[12] In 1907 he was created a Baronet, of Llanarth and Treowen in the county of Monmouth.[13] On 20 June 1917 he was further honoured when he was raised to the peerage as Baron Treowen, of Treowen and Llanarth in the County of Monmouth.[14]


Lord Treowen was married on 31 July 1873 in London to the Honourable Albertina Agnes Mary Denison (22 September 1854 – 20 October 1929 London),[15] youngest daughter of the Albert Denison, 1st Baron Londesborough (himself a son of Henry Conyngham, 1st Marquess Conyngham and his wife, a mistress of George IV) and his second and younger daughter by his second wife, the former Ursula Bridgeman (later Lady Otho FitzGerald; she died 1883). Lady Treowen founded and was the first President of the Ottawa Decorative Art Society. She was President of the Woman's Humane Society, and the first President of the Humane Society of Ottawa, and, had cabmen's shelters erected in Ottawa. As a member of the Band of Mercy Union, in 1892, she championed a resolution protesting against the use of the check-rein, and agreeing not to use or hire horses that were check-reined. She urged the erection of a national monument to Laura Secord. She was the honorary Secretary to an organization that raised a fund by the women of Canada to present a wedding gift to the Prince and Princess of Wales.[16] Lord and Lady Treowen had two children.
