• Notes: According to Deidre Johnson's terrific website on 19th century girls juvenile fiction, Massachusetts-born author Myra Sawyer Hamlin (1856-1927) wrote a five-volume series of juvenile fiction centered around Nan from 1896 to 1908. Persis Putnam's Treasure was the final book in the series. ... A one-sentence review of Persis Putnam's Treasure in the American Review of Reviews stated:
  

  "'Persis Putnam's Treasure' (Little, Brown & Co.), is a story of Nan's camp and many happenings in outdoor life, appropriate for girls of fourteen to sixteen."

  St. Nicholas Magazine, however, stated that the book about the "happy lot of girls" was for ages 11 to 14. It's possible they were all just making it up as they went.
