Hi Judy here are a few of the web sites I use for DNA info, some of them are family sites but still have explanations of the DNA origins and identification process. http://www.kerchner.com/dna-information.htm http://www.mun.ca/biology/scarr/Daughters_of_Eve_in_Newfoundland.html https://www3.nationalgeographic.com/genographic/index.html http://blairgenealogy.com/dna/dna101.html http://groups.yahoo.com/group/ISOGG/ http://www.dnaftb.org/dnaftb/ http://www.answers.com/topic/the-seven-daughters-of-eve http://www.duerinck.com/genetic.html There are obviously many many more. I did see a website that showed the haplogroup spread by percentage in Europe but cannot seem to locate it now. Best wishes. Ed Barbour ----- Original Message ----- From: "Allan B.
