This is a comprehensive survey, undertaken over a period of more than 25 years, of virtually all printed sources that lead to these royal lines. A survey on this scale has never before been attempted. The result is a book that quantitatively and qualitatively redefines this area of genealogical research and outlines--definitively to date--American genealogical links to medieval kings and their "dark age" and "ancient world" forebears. It summarizes all pertinent research published through mid-1993, and is far and away the most comprehensive treatment of the subject in print. Of the 570 colonists treated in this book, 348 came to the American colonies and left descendants, in some cases now numbering over a million, but almost always many thousands. Among the progeny of each of the 348 is at least one figure in the "Dictionary of American Biography," the authoritative work covering the 18,000 most important people in American history who died before 1972. The remaining 222 immigrants (colonial governors or other officials, "Great Awakening" or Revolutionary figures who often returned to Europe, and some 19th- and early 20th-century notables) collectively suggest much about distant kinships of living Americans and the total contribution to American life of persons of royal, noble, and gentle ancestry.
