This section records the family trees of the consorts of the British Sovereigns of the twentieth century and their heirs, Spencer, Greece, Bowes-Lyon, Teck and Denmark, all being common ancestors of the eventual heir to the throne, Prince William of Wales. In a new section, the family of Camilla, Duchess of Cornwall is now included. The book traces the descendants of their ancestors downwards through up to five generations, and includes a wide variety of British noble and commoner families, as well as those of many of the Royal Houses of Europe. In this edition, the research of the family of Diana Princess of Wales is greatly widened, identifying a further wide range of relations. Extending to 213 pages, the book is cross referenced both within itself, and to the Master Volume, and each section contains a detailed index.
