my mother (whose maiden name was Marshall but no relation!) worked as a secretary for Joan Grant in about 1935. She had very happy memories of this time, and seems to have been very fond Joan's daughter Gillian, then aged 6.Among my mother's papers. there is a story about a baby goat called Rosemary acquired for Gillian's birthday! I remember reading and enjoying several of Joan Grant's books when I was younger but sadly no longer have copies.
