Thank you so much for your reply, that will help me piece it together. I will try to explain about mtDNA. It is mitocondrial dna, which is passed down through the mothers, men have their mother's dna but cannot pass it on. Finding out your mtDNA allows you to find the deepest roots from where your ancestors came from thousands of years ago, they can trace the route that they followed. In my case I had four markers and they could tell me how many thousands of years ago my ancestor lived and what part of the world she was in at the time and so on. Finding out your maternal line, and for men their paternal line can sometimes prove what that person's ethnicity. In the case of a cousin of mine, we share a common ancestor which has been debated, was she Native American or wasn't she? Well she was lucky enough to have an unbroken maternal line to her. She had her mtDNA tested and was found to be Native American so that proved our common ancestor was Native. Matter of fact there is a story she has written which can be found in a few places on the net, if you would be interested in reading it let me know. She had no idea she had Native in her till she did the test. It's something many of us find very interesting to know about our ancestors from long ago. It's a National Geographic Genetic study on human migration that we decided to give it a try. So when we find out what group we're in we can no more about ourselves and our ancestors. Sorry to be so long winded, it's takes time to explain it. There is so much more to it and would take alot more writing to explain the whole thing, I hope this helped.
