David, born on 31st March 1892, was the first born son of Andrew Anderson, a tailor from Scotland, and his wife Mary Emily Herron from South Shields. Their children were all born in Sunderland; Isabel in 1890, David in 1892, Mary Winifred in 1900 and young Alan in 1902. The 1901 census shows the family living in Humbledown View, Ashbrooke, Sunderland, and at some point prior to 1908 David was in London where he spent two years with the Queen’s Westminsters, an infantry regiment of the Territorial Army. In 1910 Andrew emigrated with his whole family to Canada, arriving in Quebec on 31st October, having sailed from Liverpool on board the SS Canada to settle in Toronto.

David lost no time in becoming involved again with the military and became a member of the Governor General's Body Guard, an active militia unit, for three years, and then part of the 12th York Rangers for three months. On 13th November 1914 David, who had been working as a traveller, enlisted in the Canadian Expeditionary Force in Toronto naming his mother of Thomas Street, St. Marys, Ontario as his next of kin and making mention of his previous military experiences in England and Canada.

Because of his previous experiences David was appointed Lieutenant in the 220th Battalion and became part of the second contingent of Canadian soldiers to leave for England in May. The summer of 1915 was spent in training at Shorncliffe on the Kentish coast and in September 1915, the Second Division, under the command of Major-Gen. R. E. W. Turner, left for the front where they joined the First Division in the southern portion of the Ypres salient.

The first heavy fighting in which the Canadians were engaged was in April 1916 around the craters at St. Eloi, at the southern end of the Ypres salient, and it was near St. Eloi ,in an area known as The Bluff, that Lieutenant David Stewart Anderson was killed whilst leading a raiding party on 28th June 1916 and his place at the front of his men was taken by his own cousin Lieutenant Lionel Heron.

David Stewart Anderson is buried in the Lijesenthoek Military cemetery, Belgium. His three war medals were sent to his father in Toronto in 1921.

David Stewart Anderson is remembered at Sunderland on S140.048 part 9 page 200, the Canadian Virtual War Memorial and page 46 of the Canadian Book of Remembrance.
