A cautionary note

[Iowish]

I did 23andme over 6 years ago. I did it because my 3rd cousin wanted to do a family DNA study. Since he is descended from "double cousins" 3 times over, he needed at least 1 3rd cousin from each of 6 different lines. I was the first 3rd cousin from our shared line he met. He gifted me a test kit. In spite of starting out with over a dozen relatives from that family (paternal grandfather's) in the test, I have made the most discoveries I have been made have been through my maternal grandmother's family.
