He was a great-nephew of Rev James Campbell (1789-1861), parish minister of Traquair, and consequently related to Rev George Campbell (1827-1904), minister of Eastwood, and to the Very Rev James Montgomery Campbell. World War I On the outbreak of World War I in 1914 Macmillan enlisted as a private in the 9th (Glasgow Highland) Battalion of the Highland Light Infantry and served in Belgium and France, spending 16½ months in the trenches.
