There is a book in the Library of Congress by Eunice Stacy. It was published about 20 years ago, I believe. She published some copies after the original came out. The family home on the Isle of Man is still standing and was built, I believe, in the 1400's. It recently was sold out of the family. I come from a part of the family that moved away from the Charles Christian family in North Carolina. My family migrated to Georgia, but the genealogy shows we all had the common ancestor of Turner Christian. Hope this helps you.
