Early Life
Raymond Harvey Lodge Joseph de Montmorency was born on February 5, 1867, in Montreal, Québec, the eldest son of Raymond Harvey de Montmorency, 3rd Viscount Frankfort de Montmorency, and his wife, Rachel, the daughter of Field Marshal Sir John Michel, a major-general in the British Army. De Montmorency—the father—served in the Crimean War (1854-55), the Indian Mutiny (1857-78), and the Anglo-Abyssinian War of 1868, attaining the rank of major-general.
Education
Very little is known about de Montmorency's years in Canada. He was educated at Malborough College in Wiltshire, England, then attended the Royal Military College, from which he graduated in 1887 before joining the Lincolnshire Regiment in September of the same year. He was promoted to lieutenant with the 21st Lancers in November 1889, then appointed adjutant of the 21st Lancers in 1893.
Sudan Campaign
While still a lieutenant, de Montmorency served during the Sudan Campaign (1881-1899), and was in action during the Battle of Omdurman (also known as the Battle of Khartoum of 1898, to avoid confusion with the Battle or Siege of Khartoum of 1884-85), on September 2, 1898.
