by Mary Constance Du Bois
Born on March 28, 1879, and active in the early 20th century, Mary Constance Du Bois wrote historical fiction and adventure stories for younger readers. Library and catalog records confirm works including Elinor Arden: Royalist (1904), The Lass of the Silver Sword (1909), The Girls of Old Glory, and White Fire (1923), showing a career built around vivid, past-set tales of courage and loyalty.
Her fiction was published by major houses of the day, including The Century Co., and several of her books were illustrated editions aimed at a broad juvenile audience. The surviving record suggests a writer especially drawn to dramatic historical settings, where youthful characters could take part in political conflict, wartime suspense, and personal tests of character.
She died in 1959. Although she is not widely known today, her books still attract interest through library collections and digital archives, where readers can rediscover her lively, old-fashioned storytelling.
