author
Best known for retelling classic nursery tales for children, this little-known writer appears in public catalogs mainly through simple, illustrated story editions now widely available as reprints and ebooks.

by Mary Holdsworth
Mary Holdsworth is a fairly obscure author, and reliable biographical information about her is limited in the sources I could confirm. Public book catalogs and library-style listings consistently connect her name with children's retellings such as Sing a Song of Sixpence, along with other fairy-tale collections.
Because solid author-profile sources are scarce, it is safest to describe her as a writer associated with children's story adaptations rather than make stronger claims about her life or career. Her work seems to survive today chiefly through reprints, reader catalog pages, and public-domain ebook listings.
