Mary "May" Hughes (1860-1941) was an English social worker in Whitechapel. Born at 80 Park Street, Mayfair, Mary was the youngest daughter of Thomas Hughes, Christian Socialist and author of Tom Brown's Schooldays. In 1895 her uncle died, and Mary went to live with her sister Lily, wife of the Rev. Ernest Carter, in Whitechapel, East London, and soon joined the Board of Guardians for Stepney. After her sister and brother-in-law drowned on the Titanic, in 1915 Mary moved to live with friends, Doris and Muriel Lester, in the buildings that were later to become Kingsley Hall, Bow.
