My husband is about 40-60% Native American, depending on which engine we run it through (Family Tree DNA or Gedmatch's various engines). His mother is from Ecuador, and his father is Mexican from the Sonora region, in which several tribes from Mexico as well as North America live (eg. Aztec, Pima, Seri, Apache, Yaqui, etc).
Are there any tribal DNA groups out there that we can join, similar to the Family Tree DNA Projects (eg. https://www.familytreedna.com/groups/mexico-amerindian/dna-results), in which you can compare DNA with others to try to narrow down more specifically which tribes?
GEDMATCH has a feature that estimates % of tribal DNA but that's as far as we've been able to get (analysis of autosomal show primarily Apache, Aztec, and some Southern California tribes).
We seek ways to find connections to specific tribes.
