“Genetic Communities” shows 95% confidence re Early Settlers of Eastern NC

Ancestry.com debuted a new feature this year, and my results indicate that their confidence levels are very conservative. With 3 of 4 grandparents with roots in northeast NC it was no surprise to see a 95% certainty of my connection (649 matches out of 79000 members of this “genetic community”) to Early Settlers of Eastern North Carolina. I was surprised that my one northern grandparent caused a mere 20% confidence that I belong to the Early New England and Eastern Great Lakes genetic community, even though there were 140 matches.
