The 1901 Census of Canada tells us that the Armstrong family was living in the District of Nipissing, Ontario.The household consisted of Head, John Armstrong, 49, born 31st December 1851 in Ireland His occupation was Farmer. His wife, Mary Armstrong was 35 years of age. Their listed children were Thomas E. 16, Cathrin, 14, Reuben J. 14, and Robert Wesley 9.
