I just received my test results a few day ago. There are several things I do not understand but I will just deal with one at a time. I have 17 people in a Circle with 6 of them being genetic matches. Most of the 17 all match back to the same person who was born in 1776. Most all of us have that persons father in our trees. He was born in 1742. Why do we not match back to him?
