I just saw your posting re George Henry, and I have been having the same problem with him. My brother-in-law is a descendant of George, and I am researching his family. I know that George served in the Civil War, but have no idea what the circumstances are surrounding his immigration from Faial. ALso, have you had any luck tracing back Rachel Virginia Tryon's family? They seem to be connected to the Tryon's of Connecticut, but I am not sure how accurate any of this information is.
Good luck with it all!
