Great episode! My experience with DNAC is quite similar, and completely positive.
When I was first tested over 10 years ago, I was convinced many of my matches, especially the South Asian and East Asian matches were false positives misidentifying my native American genetics. Years of detailed genealogical research showed that DNAC’s analysis was accurate, and the paper trail matches the genes.
As genealogists, DNAC is the only testing service we recommend to clients.

Hello Brian, What is your company name for genealogy? Been thinking of getting professional help on at least one line of my tree.
Thank you.

Sometimes a new set of eyes on the problem helps, sometimes it’s a different problem-solving approach to break through a wall, or at least go around it!

Thanks. This awesome. I did my heritage DNA test looking for Cherokee since I’d met half Cherokee aunt in Decatur Georgia when I was 12. Seen pictures of her mom, my great grandmother full blooded and I have a picture of her son, my grandfather whom I never met. Knowing the history I was shocked to not see Cherokee in the results. Kenya Ethiopian Egyptian Saudi Arabian Turkey Iran Iraq Afghanistan Pakistan Norway Finland Italy Southern Asia and I was told all the different Jewish cultures were practiced throughout these places. From what I’ve learned so far Cherokee is probably true to aunts witness. Her mom married a black man to keep from being put on a reservation.
