The February 24 1928 edition of the Toronto Daily Star contained this brief notice of a church lecture:

Victoria Demarest (1889-1982) was the granddaughter of William Booth, founder of the Salvation Army. She founded the World Association of Mothers for Peace in 1946, following the death of her son in World War II. The New York Times has her obituary; for what it’s worth, there’s no reference to race suicide, racism, or eugenics in it.
