An author and former canonness. Born in Stourport in 1893, Baldwin entered an enclosed order of Augustinian canonesses in 1914. In 1941, after 28 years, she left the order to live in a cottage at bottom of Flagstaff Cottage, Lamorna, the family home of Samual Lamorna Birch and his daughter Elizabeth Lamorna Birch.
Here she met the artists and inhabitants of Lamorna, including Ithell Colquhoun, who recorded their meeting in her own memoir of Lamorna. Having given Baldwin a copy of her novel Goose of Hermogenes, Colquhoun reported Baldwin's shock at its contents, a shock from which their continued friendship apparently never quite recovered. Baldwin wrote an autobiography as well as several novels. By the 1960s, she had moved away to the Channel Islands. She committed suicide in a nursing home in 1975.
