Margaret Sinclair was a Scottish Catholic nun who lived from 1900 to 1925. After being baptized at St Patrick's Church, she worked as a French polisher apprentice and in a biscuit factory before entering the Colettine Poor Clares in London. Adopting the religious name Mary Francis of Five Wounds, she lived a life of devotion until her death from tuberculosis. She was later recognized for her holiness by the Catholic Church, receiving the title of venerable from Pope Paul VI in 1978.
