Mary Clarissa "May" Byron was a British writer and poet, best known for her abridgements of J. M. Barrie's Peter Pan books. She published under the names May Byron, M.C. Gillington and Maurice Clare. Byron specialised in writing biographies of great composers, poets and writers, before going on to rewrite some of J. M. Barrie's works for younger readers, to write poetry, and to write cookbooks.
