Fred, there is a lot of documentation on the Rivenbark line. Audrey Rivenbark has put it into a book "Rivenbarks of Eastern North Carolina." There are many Frederick Rivenbarks in the book. If you want to e-mail me directly I can determine which one is yours and send you the information out of the book. The book goes back to the mid-1700s as far as lineage. She also included the surnames of those who intermarried into the Rivenbarks. If I can be of assistance, let me know. Brenda
