Volume I of this three-volume set includes a 193-page Introduction and Appendices and covers the descents from kings or sovereigns who died after 1307. Most Americans with sizable New England Yankee, mid-Atlantic Quaker, or Southern "planter" ancestry are descended from medieval kings-of England, Scotland and France especially. This three-volume set tells you how. Outlined on 1,084 pages of charts are the best royal descents-from the most recent king-of 900 (actually 993) immigrants to the American colonies, Quebec, or the United States who were themselves notable or left descendants notable in American history. This second edition expands the 2018 first edition by 23 immigrants-with over a dozen considerably revised and over 500 pages in some way improved or corrected. The second edition is also a comprehensive survey of virtually all printed sources that lead to these royal lines. It summarizes all pertinent research published through mid-2022 and is by far the most comprehensive treatment of the subject in print. The 501 colonial immigrants whose "best" lines are charted in this work include almost all colonists from whom royal descent is considered proved. Of these 501, 235 left ten or more notable descendants each and are ancestors collectively of probably over 100 million living Americans.
