Richard...I am very skeptical of anyone claiming to be an "authority" on someone else's family tree. I too have Pocahontas in my tree and also a controversial figure named Aaron Brock who many people say was the legendary Chief Redbird. After being called "wannabe" and "liar" amongst other things, from people who could not offer any evidence to the contrary, I have decided that their input is useless. You have, as I have, put a lot of time into research and who needs those jokers. You, my fellow descendant, are an authority on your family tree, just as I am on mine! We are entitled to bragging rights until someone shows us PROOF that we are wrong....not just words!
PS: The book "Pocahontas Descendants" is VERY incomplete and is not the "final word" on the subject!
