A distinguished work, it provides pedigrees of descent from Charlemagne that can be proved without a doubt. The progeny of Royal Houses of Europe that trace back to Charlemagne are listed in chronological order under their respective Houses. Then, individual chapters list American families that link up with one or more royal lines, and pertinent facts are given for each member of the family--birth, marriage, children, connecting lines, station, distinctions, and honors.
I am using this book as a resource to validate my ancestry.com family tree. This book very difficult to follow, the format of each pedigree line is confusing, and there are no explanations on how to use the information at the beginning of the book. I wish it had been written in the normal format used for genealogy… but it is the only resource for this information that I am able to find so far.
