Once again Gary Boyd Roberts has assembled all recent royal descent research, some yet unpublished, and produced an authoritative, up-to-date compendium. In this 2008 edition, he has added twenty-eight new immigrants, so that with a few disproofs (Curwens/Corwins of Massachusetts and New York, Byes of Pennsylvania, and Edwardses, one Evans and Hugh Jones of Pennsylvania), the total covered is now 688. The 387 colonial immigrants whose "best" lines are charted in this work include all but a handful of colonists for whom royal descent is now considered proved. Among the 387, the following 180 left ten or more notable descendants each and are ancestors collectively of probably over 100 million living Americans.
