I could probably use the DNA they gave me to dig deeper but I haven't yet found the time. They do have a fun service where potential relatives can be found through DNA comparisons. So far, the best I have seen is a 4th cousin although I haven't contacted them yet. I am glad you found the blog so useful! 23andMe didn't really tell me much more than Western European.

I also have been tinkering with the idea of sending my sample in. It's so facinating. I was wondering...did the results give you an idea of what region you came from? I know it's limited on how far back you can trace your ancestry but I was watching something about a DNA company that traces back to the region your ancestors came from and ethnicity.

If I could find a female line back to her sisters (or a male line back to her brothers for that matter), then I would be able to trace their ancestry back to her. I would have to be able to show some relationship to that person though. For example, if her sister had a daughter who had a daughter who had a daughter, I would have to know that I was related to this last daughter. If I knew I was related to her, then I could trace my ancestry through her. You didn't need to preface your question…you are exactly right.

Tue, 29 Sep 2009 02:23:42 +0000 http://www.kqed.org/quest/blog/?p=3737#comment-12207 Hello Dr. Starr, Let me just preface my question by acknowledging my ignorance regarding the subject matter and to ask you for your forgiveness if I have overlooked or misunderstood any basic fact regarding gene theory. You may have addressed this in a previous post, but I am curious to know whether your great, great grandmother had any sisters with whom she shared a common mother? If she did, and if the maternal line has been perpetuated to the present day, would it not be possible to examine their mtDNA for the existence of the Native American roots that you are attempting to confirm? This, of course, assumes further that the remaining line (if they exist) are willing to provide a sample. :) Paul Hello Dr. Starr,
