Dear 100 Hour Board,
In my family history research I've been tracing my paternal line following ancestors that shared my last name. When I get to my dad's great-grandfather, though, I hit a wall. Until recently, that is. I have a family that I think is probable for being his parents and siblings but the evidence I've found has not been conclusive. My dad recently sent in for the Ancestry DNA profile and it got me thinking about another possible route of investigation. I've been in contact with someone who is a descendant of this ancestor's potential sibling (I assume brother since we share a last name) but I'm not sure how many generations removed he is. What are my potential options for overcoming this roadblock in my research, DNA-wise? I've heard from some that the Ancestry DNA profile is too general and won't be enough and from others that I can use my dad's results to find a link. Is it useful or will I need a different test to establish a connection? How conclusive are these tests the more generations you go back? Will any test be useful to me?
-My Name Here
Well, according to Ancestry's website, the test can be used to identify distant cousins, as long as they've also taken the test. So that's probably an option. Although that's somewhat separate from the main feature of telling you your general ethnic background.
FamilySearch has an interesting article about DNA testing and how it can help.
