Gladys and Osborne Hedley's eldest daughter was Gladys Olwen Hedley F.R.S.L., though she was known as Olwen Hedley which was also her pen-name. She was born on 28 April 1912. From 1932 until 1939 she worked as a journalist on the Windsor, Slough and Eton Express and during the War she was a VAD in Windsor. From 1947 to 1964 she was Assistant Librarian at Windsor Castle and wrote several books on royalty and about the Windsor area. These included: A Child's Guide to Windsor Castle (Beric & Co. Ltd: Child's Guide Series): Round & About Windsor [1930's, Oxley and Sons - owners of The Windsor, Slough and Eton Express], Windsor Castle (1967, 1972, Robert Hale Ltd), Queen Charlotte (1975, John Murray Pub.). It is likely that many households have possessed a copy of at least one of the booklets she wrote about historic places and events for Pitkin publications. She also wrote for publications such as the Historical Magazine and a booklet, Royal Foundations of St Katharine, Ratciffe (1984). References are often made to her work by later writers.
Olwen lived for many years in accommodation in Windsor Castle but moved to London when she retired. A practised researcher, she began investigating the Owen family history some years before I did. I never met her - she died on Saturday, 29 August 1998 - but she corresponded with other members of the family and I have copies of some of her records, for which I am extremely grateful. They have greatly helped me with this project.
