I have DNA confirmed my 3x great-grandfather in the Summers line. I received a AncestryDNA match yesterday and I spent some time figuring out the connection. Usually, DNA matches don’t have their tree filled out far enough to connect. The picture shows how many grandparents we have.
My tree is a DNA tree. DNA confirming a line means I know the line is accurate to a certain point. When I attempt to figure out how I DNA connect with someone, I am trying to see which grandparents we share in common. I am more confident working in lines I’ve DNA confirmed because I know they are correct. Also, keep in mind the screenshot does not include cousins – only grandparents.
