Sir Ian Zachary Malcolm, 17th Laird of Poltalloch, KCMG (3 September 1868 – 28 December 1944) was a Conservative Member of Parliament and Chieftain of the Clan Malcolm/MacCallum. Background and early life Malcolm was born in 1868, the son of Colonel Edward Donald Malcolm, 16th of Poltalloch (1837–1930). His father's elder brother was Conservative politician John Wingfield Malcolm, Baron Malcolm of Poltalloch (1833–1902), who died childless and left the Malcolm estate to his brother Edward, from whom it came to Sir Ian on his father's death in 1930. He was educated at Eton and New College, Oxford. Career Malcolm served as a Justice of the Peace (Argyll, 1898) and as MP for Stowmarket from 1895 to 1906, Croydon from 1910 to 1918 and Croydon South from 1918 to 1919. His Labour opponent in the 1918 General Election was H.T. Muggeridge, the father of Malcolm Muggeridge. Malcolm held many diplomatic and political appointments. He travelled extensively in British India in 1901 to 1902; visited the North-West Frontier Province and Rajputana! and accompanied Lord Curzon of Kedleston, Viceroy of India, on his tour through Burma in late 1901. He was a British Red Cross Officer during the First World War in France, Switzerland, Russia and the United States. In April to May 1917 he was a member of the Balfour Mission, which was intended to promote co-operation between the United States and the United Kingdom during the First World War. He was private secretary to Arthur Balfour at the Paris Peace Conference in 1919, when he was appointed a Knight Commander of the Order of St Michael and St George (KCMG). Family On 30 June 1902 at St. Margaret's, Westminster, he married Jeanne Langtry, daughter of Lillie Langtry, the famous actress. Breaking all tradition, the bride was given away by her mother. Unfortunately, Malcolm's family was far from impressed by their new daughter-in-law's mother—it is likely they were highly aware that Jeanne Marie's father was not Lillie Langtry's first husband, Edward Langtry, but Prince Louis of Battenberg. Lillie saw less and less of her daughter. Jeanne and Sir Ian lived alternately in a house in Belgravia, London, or at the Malcolm's family seat at Poltalloch in Scotland. They had four children: George Ian (who later succeeded as 18th Laird of Poltalloch) (1903–1976); Victor Neill (the first husband of the actress Ann Todd) (1905–1977) and Angus Christian Edward (1908–1971); and Helen Mary (1918–2010).
