Yeah weird huh! I consulted a genealogist and this is what I was told:

"Based on your admixture some of your ancestors were Native and some were European [sp. Italian, Greek, and Spanish]. You are more than one quarter and slightly less than one third Native, which suggests admixture from several lines. One full Native grandparent would equal 25%, and very few people have been full Native for generations."

I shared my DNA file with several projects online and was able to get matches for nine different tribes with Cocopah having the largest percentage of markers.
