Supporting roles—how DNA and family trees work together.
A DNA test can provide powerful confirmation for your family tree research and can even guide you in directions you didn’t anticipate. For instance, if your tree leads you to believe that your family is from Ireland, your DNA ethnicity results may back that up. On the other hand, if your records trail goes cold, your DNA results may give you a clue on where else to look.
AncestryDNA, in particular, can provide you with even more powerful features when paired with a family tree. Suppose your grandmother told you that one of your ancestors sailed across the Atlantic with the Pilgrims, but you had never been able to find out if the story was true or not. After you submit your AncestryDNA kit, we compare your DNA with millions of tests in our database and give you a list of DNA matches to explore—people you are likely related to. If some of them have Pilgrims in their family trees, then your grandmother may have been right after all.
