Check out this site for dna information. It has some of the clearest explanations and examples I've seen: https://www5.nationalgeographic.com/genographic/ Our results from the 20 or 21 participants we have this far have been encouraging (I intend to get those results on the web so everyone can see them). Please consider joining the project yourself or having someone you know join it. We need additional data to resolve issues for distant branches. sincerely, Tom Cloud
