Big Announcement! The Theory of Family Relativity is now live at MyHeritage


This is first big announcement at RootsTech, and it's a game-changer for genetic genealogy! I've played with it for about an hour this morning and am very impressed. Learn about it below, register for its free webinar, and then check out your new DNA theories in the DNA Matches area at MyHeritage.com.

TEL AVIV, Israel & LEHI, Utah--(BUSINESS WIRE)--MyHeritage, the leading global service for family history and DNA testing, revealed today its latest innovation in genetic genealogy — the Theory of Family Relativity™. This technology offers users, for the first time ever, theories that utilize nearly 10 billion historical records and family tree profiles to explain DNA connections. Until now, family history enthusiasts used two distinct domains for making discoveries: the paper-trail world of records and trees, and the biological world of DNA connections. Now, MyHeritage has combined these two domains and integrated them seamlessly.

The Theory of Family Relativity™ is based on a big data graph that connects billions of data points drawn from thousands of databases on MyHeritage, in real time. Every node on this graph represents a person, and every edge depicts a blood relationship between two individuals that is described in a family tree or a historical record; or a match between two tree profiles that are likely to be the same person; or two records that are likely to be about the same person. These connections between people and records are established by MyHeritage’s industry-leading matching technologies. MyHeritage engineers and algorithm experts led by the company’s CTO, Sagi Bashari, developed a unique approach that allows the big data graph to instantly compute all paths between millions of blood relatives. The Theory of Family Relativity™ draws upon this resource to construct the most plausible theories explaining how pairs of people linked by a DNA Match on MyHeritage are related, using family trees and historical records.

Previously, users who took a DNA test looking to find relatives were faced with puzzling lists of thousands of distant relatives, without many clues explaining the DNA connections. Now, for a growing percentage of these DNA Matches, theories are provided by MyHeritage that explain the precise relationship paths using trees and records. In these theories, not only does genealogy illuminate DNA connections, but DNA also helps separate fact from fiction in the genealogy and shows which tree and record connections appear to be correct.

This technology uses millions of family trees on MyHeritage, as well as the World Family Tree on Geni, which is replicated daily to MyHeritage, and the single family tree of FamilySearch, which is also replicated daily to MyHeritage under license. This combination results in the most comprehensive family tree traversal available today. Additionally, the technology utilizes billions of historical records on MyHeritage, including all census records, as well as the MyHeritage Record Detective™ technology that indicates whenever two records are about the same person. For example: a theory that explains a DNA Match between two users can begin in the family tree of the first user, traverse through a series of matching trees into a census record, continue to a household relative, who then matches into another tree, until the path completes with the family tree of the second user. MyHeritage displays the complete path of every theory, and explains every step along the way, allowing the user to verify its accuracy. Each theory is presented with a confidence level that is based on the confidence of the matches used to construct it.

“Our new technology is a game changer in its scope and power and is a tribute to our passion for developing the best genetic genealogy tools for our users,” said Gilad Japhet, Founder and CEO of MyHeritage. “Using genealogy to explain DNA Matches, and using DNA to validate genealogy matches, combines the best of both worlds. We expect this technology to help people make new discoveries in their family history. With every day that goes by, this technology grows even more powerful as more tree profiles, historical records and DNA kits are added to our global database.”

The Theory of Family Relativity™ feature is included for free with all Premium, PremiumPlus, and Complete subscriptions on MyHeritage. Individuals who upload their raw DNA data from other testing services to MyHeritage who do not have a subscription can pay a one-time fee of $29 per DNA kit to unlock the Theory of Family Relativity™ and the full range of advanced DNA features offered by MyHeritage.

And how do you make a change in your tree when you find a DNA-based error.


Can you elaborate? What do you mean by a dna-based error?


Are you sure the Theory of Family Relativity is live for all Complete subscribers? I just renewed my subscription last week but do not find a link to it on my site. Perhaps the program is still in beta.

Hi Ed - yes, it should be live for everyone I believe. Go to your DNA matches page at MyHeritage, click on the Filters link, and then under the All Tree Details menu, click on "Has Theory of Family Relativity".

This is a wonderful program. At last, it has uncluttered, side-by-side Theories I readily understand.
The daily deluge has ended.
The best feature is to just look at the Theories and the
tree and really know just how we are related!
My Heritage you have placed us "ahead of our time" and
given me back mine.

When I review a theory and and disprove a match between 20 people - eg a 20% match that is false - is there a way to disregard the theorgy?

Ed Karsch:

I asked the same question on another blog discussing the new feature. I was told there that you will only have a link if the website has any "theories" to show you about your matches. For perspective: this particular blogger manages 12 different DNA kits (kits typically get thousands of matches conservatively) but has only THREE "Family Relativity theories" out of all the matches on all 12 kits! I am not sure if these numbers will grow as time goes on and the algorithm continues to search all the trees and records available, but we will see. It may be similar to Ancestry's DNA Circles which are constantly changing in number. Hope this helps!
