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). Mary later became one of the first two female announcers on the
BBC Television Service (now BBC One) from 1948 to 1956, during which time she became a household name in the UK. She died on 13 October 2010 at the age of 92. ==Publications==
