DNA is really your best tool to prove Your Line. Think on this .... A. if you do not match with any of the Chase DNA project or also the Dalton DNA Project and you come with a Y Line that matches the James DNA Project,you may have a chance. You are counting onShorty James DNA to match you also. Have you checked the James DNA project for his matches? What has happened to the four in your family that matched? Did any of them check out the James DNA project?
