What surprised me was no Native American showing for me (it is confirmed that I have Native American heritage through a Mohawk ancestor, Ots-Toch born ca 1622 in what is now New York state), and that I have a small bit of East Asian. However it's important to note that one test isn't the final answer, especially when searching for confirmation of heritage from several generations back.
So it doesn't concern me at all that my Native American heritage doesn't show in the 23andMe.com results. The raw data from my brother's DNA test on Family Tree DNA also did not show our Native American heritage until I had it analyzed by Professor MacDonald, who is conducting his own study on DNA and has a different set of algorithms for providing results. Then it showed my brother as having .7% Native American heritage.
And the icing on the cake is that my brother's DNA test from 23andMe.com also showed our Native American heritage at .7% (with East Asian at .1% just as mine is)
My brother's test from 23andMe also showed .7% Iberian which is the region of Spain and surrounding areas. We know from his raw data that he has a rare mutation which is known to have occurred when a group of Basque men went up to help build Hadrian's Wall between Scotland and England. So that fits with the finding of Iberian heritage.
