This book has some correct Caldwell info and interesting things I have not seen before. It also contains some misinformation though due to Gustave Anjou previously making up false things about the Caldwell Pedigree. Unfortunately earlier Caldwells did not know this and took his word. It was debunked later on the Barborossa Pirates, Cromwell, and Huguenot stories. I help run http://caldwellgenealogy.com/ we are making a effort to connect Caldwell's back together and clear things up.
