Not necessarily a dead end. If he has a male line descendant (that is, if he had a son who had a son who had a son, etc.), that man's Y chromosome can be tested by the folks at www.ftdna.com, the genealogical genetic testing company with the largest database, and compared with that of other men. There may be a match or a close match that could prove helpful.
