The aims of the Society are to celebrate and investigate the life and times of  Katherine de Roët, later Lady Swynford, then The Duchess of Lancaster and her ancestors, contemporaries and descendants.  The Society, which is run entirely by volunteers, publishes a journal - The Katherine Wheel -  and organizes a series of occasional indoor lectures in the winter and outdoor visits in the summer months.  It also encourages and supports research projects whose purpose is to investigate various locations and persons associated with Lady Katherine.  These may be carried out by members of the Society or students of History in various educational establishments.
