The book begins with the description of the family history of Claytons, which serves as the foundation. Then the book follows it up through its various changes to the present time. It gives an account of how Rollo made peace with the King of France, and Dukedon of Normandy was confirmed. It tells about the details of that settlement after a thirty years war. From that time, Normandy began to flourish, and during the time of its first six Dukes, it was one of the richest provinces in the world, notwithstanding its many wars. In this book, the author devotes a considerable space to the account of Ancestry of Mary Mainwaring. The details about the Pennsylvania Branch of the Clayton Family are also mentioned. The book includes an extract from the family Bible of the Late Hon. John M. Clayton. It contains Genealogical Table for six generations of the Delaware Family of Claytons.
