Update to Theory of Family Relativity™

Update to Theory of Family Relativity™

If you’ve been trying to figure out how some of your DNA Matches are related to you and haven’t received any Theories of Family Relativity™ yet, you just might be in luck.

The Theory of Family Relativity™ leverages all the data available on MyHeritage, such as family trees and historical records, to provide you with plausible theories as to how you may be related to a given DNA Match. We run updates and refresh the data periodically, and we’ve just refreshed the data again this week.

MyHeritage’s databases have grown considerably since the last update, including millions more family trees and over 2 billion additional historical records (bringing us to a total of over 12 billion records). That means that there’s an excellent chance those of you who have been stumped or stuck on certain DNA Matches may receive answers and new insights about your ancestors and family relationships.

Theory of Family Relativity™ update by the numbers

The total number of theories has increased from 14,260,864 to 20,330,031 — a 42.6% increase.

The number of DNA Matches that include a theory increased by 42.5% from 9,964,321 to 14,201,731.

Sometimes we arrive at a theory through multiple paths, indicating a strong theory and providing additional supporting evidence. After the previous update, there were a total of 115,106,944 paths. This update increased the number of paths by 40.5% to 161,762,761.

The number of MyHeritage users who now have at least one Theory of Family Relativity™ for their DNA Matches has increased by 33.6%.

How to find out if you have new theories

 If we have found new theories for you in this update, you’ll see a banner about the Theory of Family Relativity™ at the top of your DNA Matches page. Click “View theories” to see all the theories we’ve found, both old and new.

This banner, indicating that you have new theories, will be available for a few weeks, after which you can access your theories by going to your DNA Matches page. 

Whenever a DNA Match has a theory, this will be indicated in the DNA Match card. You can also filter your DNA Matches to see only those with a Theory of Family Relativity™ by clicking on the Filters icon. In the first group of filters, select “Has Theory of Family Relativity™.” 

You will also see a “NEW” badge next to new theories that were just added. This indication will appear for 30 days. 

Theory of Family Relativity™ is a premium feature that requires a site subscription on MyHeritage (Premium, PremiumPlus, or Complete). Users without a subscription will still see all the theories that we found for them, but when they click on the theory to view the full details, some of the information will be hidden. Users who upload their raw DNA data from another testing service to MyHeritage and do not wish to purchase a subscription can pay a one-time fee of $29 per kit to unlock all advanced DNA features offered by MyHeritage, including Theory of Family Relativity™. Learn more about our subscription plans.


The Theory of Family Relativity™ can be a game-changer for people searching for new family members and genealogists trying to break through brick walls. It can help users instantly solve mysteries that may have been baffling them for months or years.

    Thanks so MUCH for the update. I have been waiting 2? years to get ANY Theory of Family Relativity hints and I have a tree of 60000+. I would never have found the link for John Smith with my brothers. Keep up the good work.

    Family relativity is great however sometimes the links can be incorrect due to duplicated names or similar paths.
    Could you allow for a deny link or confirm type of feature??

    It has been Brilliant so far in helping me, as my Knowledge of D.N.A is somewhat lacking. Finding the time to learn about D.N.A is a major task.

    A lot of people did dna on my heritage but they have no tree or they have just uploaded 2-3 relatives. They probably have a tree on another platform. If they Would upload their gedcom on MyHeritage there would be much better use of the dna matches

    I must compliment My Heritage on the accuracy of their ethnicities matching. On receiving my DNA results I was puzzled to find a 0.8% Eastern match amongst my European and English background. Much research uncovered the fact that in the late 1600’s a freed slave from the East Indies married into my ancestry! And I was actually able to obtain the details.

    My husband grandmother Grace Hannah Cowell Petry Post was adopted we think it was a family members baby but Jesse and Martha Cowell registered her as there daughter at about 3 months at the towanda pa court house then did adoption papers just before she was 18
    I figured they wanted to make sure no one took he inheritance away from her so some of the family knew who she belonged too.

    There should be a way to ignore connections to trees with incorrect people or relationships.

    I would like to find an easy way of tracing just the paternal or maternal sides of a family as a way of finding a missing relative. In my case, a missing grandfather on my father’s side.

    Go, Dagney! I am proud to see you flaunting your abilities, not the your disabilities, as you hit 107. Since my youth, when I found I had two great-grandmothers, my father’s grandmothers, lived to be 97 and 102, I have wanted to reach 100. I’m still just a youngster, only 88, but I am so glad I have enough knowledge of computers to write, correspond, Zoom, and do a million other things on my computer. The hours go by so quickly when I am on my CP I find myself at 3 PM, still in my pajamas and not even noticing I’ve skipped lunch. Usually is a call to use the bathroom that wakens me from my fascination with technology. My tech-man is my fourteen-year-old great-grandson, Samuel. He’s very knowledgeable. He amazes me, how fast his mind is, and how easily he learns things. I’m delighted to live fairly close to him now, instead of across the country, as I did until last fall.

    I want to get the young people involved in tracing their family, but it will be a tough search. Their ancestors were not famous. Some never held a job. Two were street-people who lost contact with their families. We sometimes can go back one generation, but often hit roadblocks there. One grandmother was raised in an orphanage in New Jersey. We do have her maiden name, and may be able to find her, eventually, but it’s not like people who have people with more documentation in their lives, like military or employment records. I doubt these people ever were the subject of newspaper articles. They probably lived in rental properties, if they had a stable home. It only makes the search more of a challenge, but my time is running out. I have only about 12 years left. I have been doing genealogy for about 55 years. Before that, I simply saved old letters and other correspondences in a big box. I’m glad I did that! I moved frequently, but always moved that box with me.
