No longer. In the last 5-7 years genetic genealogy has come into its own. By testing a man's Y DNA, which we inherit from our fathers, one can determine one's patrilineal ancestry quite well. Go to www.familytreedna.com and take a look at their FAQ. It's often a very helpful adjunct to traditional genealogical methodology. And often more reliable. A paper trail may contain misrepresentations based on wishful ancestry, but DNA doesn't.
