Virginia, Specifically which of these people are you interested in? As you probably know, the Thomas Cook and Miley Marcum Cook that you mentioned are the subject of the book on the Cook family in Bedford County, TN by Jerry Wayne Cook. Jerry Wayne Cook lists his Cook line as being of English descent. However, there are other Cooks in Bedford County, TN at the same time who are definitely not of English descent. It also appears that some researchers have gotten these two Cook lines intermingled so be prepared for more than the usual frustrations when dealing with these people. Robert Nicholson
