re: How many of you are really Native American?

I was always told I had a great deal of Cherokee but ancestry.com said southwestern US and South American tribes. I'm not quite clear on how to translate their "markers" to percentages.My dad's whole family had the look but I look just like my Mom's Irish brothers. All my maternal great grandparents were born in Ireland. Results showed traces of Portuguese and Pacific Islander too. Lots of Scandinavian too. From the time of Julius Caesar to William the Conqueror the people of the British Isles became noticeably taller and fairer. Cause "We're the Vikings and we're here to party".
