MyHeritage Updated Theory of Family Relativity

MyHeritage is excited to share that they just completed an additional update to the data for their ultimate genetic genealogy tool, Theory of Family Relativity.

Theory of Family Relativity can save you countless hours of work figuring out how you might be related to your DNA Matches. It pulls together billions of data points from across the 86 million family trees and 18.2 billion historical records on MyHeritage to bring you plausible theories about your relationship paths to your DNA Matches.

These calculations are run on a periodic basis. Since their last update, many new DNA kits, family tree profiles, and historical records have been added to MyHeritage. This means that the number of theories, the number of DNA Matches that include a theory, and the number of kits that have a theory have all increased significantly.

If your DNA results came in relatively recently, or if you’ve been waiting to receive a theory, there’s a good chance you might receive one as a result of this update.

The New Update By The Numbers

25,636,711 Theories of Family Relativity were added

328,439 kits that didn’t have any theories previously now have at least one 

233,297 additional users will have at least one theory following this update

Note that in this update, MyHeritage only added new theories and did not update any theories that existed previously.

Viewing and Analyzing Your Theories of Family Relativity

To view your Theories of Family Relativity, visit your DNA Match page. The relationship calculated by the theory will now appear directly on the match card of a DNA Match that has a theory. New theories will be labeled with a “NEW” banner for 30 days after this update.

You can filter your DNA Match list to view only matches with Theories of Family Relativity. To do so, go to your DNA Matches page and click the “Filters” button on the top right corner. Under “all tree details” on the far left, select “Has Theory of Family Relativity.” You will now see a list of all your DNA Matches that have a theory.

To view the full theory, click “View theory.” This will take you to a page that shows in detail how the algorithm arrived at this theory. 

Sometimes, MyHeritage will arrive at a theory in more than one way. In cases like these, you will be able to toggle between the multiple relationship paths. 

Confirming or Rejecting a Theory

While the theories are often accurate, they rely on Smart Matches and Record Matches, which may not always be correct. That’s why it’s important to review the relationship path for the theory and confirm its accuracy.

If the theory appears to be correct, you can click the purple “Confirm” button above the relationship path chart. If it appears to be incorrect, you can click “Reject.” Your confirmation or rejection will then appear in the DNA Match’s card in your list. (You can always undo this action if you make a mistake.)

What Can I Do To Increase My Chances of Getting theories?

In order to receive Theories of Family Relativity, you must:

Have taken a MyHeritage DNA test, OR uploaded your DNA to MyHeritage from another testing service.

Have a Premium, PremiumPlus, or Complete plan on MyHeritage OR have paid the one-time unlock fee for advanced DNA features (for uploaded DNA data only)

Have a family tree on MyHeritage that includes at least you, your parents, and your grandparents.
