We determine our common WALL ancestors and discover which Wall family lines are related to others. Our primary tool is Y-DNA, which is the patrilineal DNA, passed only from father to son. Matching another person on Y-DNA means that a two have a common ancestor along the all-male line. This usually parallels surnames. Some of our project participants do not have Y-DNA test results, and that's OK for people with some relationship to a Y-DNA tester in the project. Many of our participants have atDNA results, which FTDNA refers to as "FamilyFinder". We look for common ancestors among the distinct branches of Walls, Wall, and other spellings. DNA tells us that the spelling is not very important. Some of our ancestors didn't spell their own name consistently. In some lines, we can see the spelling changed between Wall/Walls in different generations. If you have questions about the project, or you seek testing advice, or you have any other info to share, feel free to contact one of our volunteer project admins or co-admins. You can find the contact info on this page. We look forward to hearing from you.
