Addenda There are two sorts of addenda:          (1)  Shorter Addenda—organized as a single continuous file, these mostly add information to the several genealogical descent charts published in the book (and are not yet necessarily reflected in textual discussions of information in those charts); (2)  Larger Addenda—organized as a series of separate document files, these are discussions, sometimes extended, of particular individuals and are based either on information newly found or on information in which reason for confidence has improved since the book was published. The addenda files, like the errata file, will be updated as information comes to light.  If somewhere down the trail the book is republished in a second, corrected and expanded, edition, all significant content of these files will be integrated into the text and charts.
