Enid set up a home in Chelsea with Anne Lupton (1888–1967); a sort of Boston marriage. Enid and Anne studied at Newnham College at Cambridge University where Enid graduated with an M.A. in 1911. Anne was the sister of Olive Middleton, née Lupton (d.1936). Both Olive and Anne were actively involved in women's issues; in 1910, Olive was an honorary secretary of the West Riding Ladies' Club and in 1938, Anne organised an exhibition at the London Housing Centre for the centenary of Octavia Hill's birth which was visited at Anne's own request by Queen Mary. Anne purchased a Georgian house and donated it to Lady Margaret School which Enid had established in 1917. Enid and Anne collaborated to publish works concerning the suffragette cause.
