The 1901 Census of Canada tells us that the Armstrong family were living in the District of Nipissing, Ontario.The household consisted of Head, John Armstrong, 49, born 31/12/1851 in Ireland, occupation Farmer. His wife, Mary Armstrong, 35 years of age, their children, Thomas E. 16, Cathrin, 14, Reuben J. 14, and Robert Wesley 9.
Unfortunately I cannot find the family or Robert Wesley on the 1911 Census of Canada.
Private 3040679, Robert Wesley Armstrong was drafted into Military Service. His Attestation Papers from the Library of Canada show that he enlisted at The Niagra Camp, Ontario on 4th September 1918 aged 21 yrs. 11 months. His papers state that he had previously enlisted for 7 months in the Royal Flying Corp. He was an Electrician and Phono Operator by trade. His address was given as New Liskeard, Ontario and he names his mother Mary Armstrong as N.O.K. address Box 646 New Liskeard, Ontario.

He was transferred to 12th Battalion Canadian Infantry on arrival and unfortunately contracted Influenza while at Kinmel Park Camp. He was admitted to the Military Hospital as dangerously ill on 18/10/1918 and unfortunately died the following day.
