We’re excited to share some of the advancements we’ve made to the science of finding your relatives through DNA, commonly referred to as DNA matching.
- More precise matching—We can identify DNA connections with a better level of precision and accuracy than was possible before.
What to Expect
We’ve improved the confidence levels in estimating relationships by extending the comparison methods to potentially find longer segments of DNA shared between individuals. Individual results will vary, but because of this, you may see some DNA matches that were previously predicted to be more closely related to you at a higher confidence drop down in your list or no longer appear. Also, you may have new DNA matches that you haven’t seen before. If you have taken notes or "starred" a DNA match that no longer appears on your new list, you can download information about that previous match for a limited time from the DNA test settings page.
Don’t Miss a New Discovery
With this update, we have also added a new weekly email that will notify you of 4th cousin matches (or closer). So, as new people take the AncestryDNA test, you can find out if a new close cousin is found.
Advances in the Science
What Makes These Advances Possible?
The short answer is that the 1.5-million people taking the DNA test plus the family trees they share are enabling new findings in the science of how we’re all related. Each person who takes the DNA test is connected into the vast family network of people using AncestryDNA. With each observation of relatedness in that DNA network, along with the confirmation of the family connections, our scientists are finding new methods to better predict who and how we’re related.
