Further to the enquiry about Winifred Graville of Sheffield my mother(maiden name Graville) supported Winifred in the latter years of her life and I have quite a lot of newspaper articles from the 1930’s which Winifred kept and documents and articles written by Winifred. She extensively researched the beneficial properties and folklore of plants. I am not sure what to do with this box of material.[/quote]As she was a Fellow of the Royal Horticultural Society you could try them to see if its of interest for their library and archives.
