It welcomes everyone interested in learning more about this extraordinary family. The Powys family and their friends constitute an unusually wide-ranging spectrum of social, literary and imaginative interests. The founding of the Society in 1967 reflected a feeling among Powys admirers and friends that the special quality of the Powys writings, particularly those of John Cowper, Theodore, and Llewelyn, was not sufficiently recognized. The Society publishes a substantial journal and three newsletters a year and has embarked on a publication programme. In addition it organises an annual conference, occasional meetings, exhibitions and walks in areas associated with the Powys family)
