Matthew Whitworth-Aylmer, 5th Baron Aylmer
He was gazetted ensign in 1787, lieutenant in 1791 and major in 1800, after being held in a French prison for six months in 1798. His career continued as colonel in 1810, being aide-de-camp to the King between 1810 and 1812 and then major-general in 1813. He was present at most of the battles in the Peninsular War.
North American administration
After reaching the position of lieutenant-general in 1825, he was, in 1830, appointed commander of British military forces in North America as well as Governor General of British North America and Lieutenant Governor of Lower Canada.
Lord Aylmer had no previous experience as a civil administrator and no political experience. He was unable to pacify the growing demands in Lower Canada for responsible government and, in 1834, the radical Assembly of Lower Canada passed 92 resolutions of grievance including a demand that Aylmer be recalled. Lord Aylmer exacerbated ethnic tensions in Lower Canada by favouring the English over the French. The deterioration of the situation led to his recall in 1835. His administration may have been a contributing factor to the Lower Canada Rebellion of 1837.
Return to England
Aylmer's sister Rose Aylmer was the inspiration behind the poem of that name by Walter Savage Landor.
General the Right Honourable Matthew Whitworth, 5th Lord Aylmer, G.C.B., married Louisa Anne Call, daughter of Sir John Call, Bart. on 4 August 1801. When her husband was appointed in 1830 to administer the government of Canada, as Governor-General, from February 1831 to August 1835, the couple entertained at the Castle of St. Louis, Quebec. During the cholera epidemic of 1831-32, she was interested in the relief of the sufferers. Since she was interested in education, she regularly visited and bestowed prizes in the schools. She served as the patroness of the Societe d'Education sous la direction des dames lie Quebec. She died on 13 August 1862.
