Jeff I don't know of any book on Guillaume Danos. I think what you saw was a reference which , you can get a genealogy report of of the decendents of Guillaume Danos from Brien,s data on his web site. I saw a long time ago in and article, which at that time didn't know he was one of my ancester, I didn't keep the record. What a mistake that was . Latter when I found he was my ancester, I went back to the library and couldn't find which book I had seen it in.I remember from the article that he was a gambler. Velton Guidry,
