Charles, Thanks for your interest in my book, which is still in preparation. Most of the biographies are complete, but I am still working on some of the evidence analysis that explains how I figured out where each person fits on the family tree. I also have to complete citations, indexing, etc.
I never realized that when I was ready to bring this book to completion a few years ago, so much interesting new material would turn up--stuff that I couldn't ignore! I just hope that the delay will be worthwhile to me and my prospective readers.
