Listers, Just a thought. It occurs to me that most persons participating in the dna project would do so because of inadequate documentation. Some may do so out of interest in their line, however, those who have well-documented evidence in tracing their 'tree' back to the original immigrant to America, might not need dna to 'prove' it. Interesting. This leads to the question, how can we encourage those with well-traced roots to participate, so the others in the study can compare results? (just a thought) Holly
