New Update to the MyHeritage Theory of Family Relativity™

 I received this information from MyHeritage this morning:


Time for another genealogy “happy dance”! I’m happy to announce that we have again updated the data for our “holy grail” of genetic genealogy — the Theory of Family Relativity™!

This update adds millions of new and improved theories that explain how you and your DNA Matches may be related, give you answers about relationships that have baffled you, and offer new insights about your ancestors and family relationships.
The Theory of Family Relativity™ harnesses billions of family tree profiles and historical records on MyHeritage to suggest possible relationship paths between you and your DNA Matches, helping you to break down brick walls and potentially saving you dozens of hours of research.

With this update, the total number of theories has increased from 33,373,070 to 39,845,078 — a 19% increase. The number of DNA Matches that include a theory has increased by 20%, from 22,618,962 to 27,130,989.

As MyHeritage users add more names to their family trees and as we add new historical record collections, the opportunities to receive theories will continue to grow, offering new insights to help you further your genealogical research.

You can read more about the update to the Theory of Family Relativity™ on our blog.


My number of Theories of Family Relativity increased by 37.5% - from 8 to 11.  That is out of over 9,200 DNA matches.  That is 0.12% or 1 out of every 836 matches.  The last time MyHeritage updated the Theory, the number I had decreased from 12 to 8, so I'm almost back to where I started two years ago.

Disclosure: I receive a complimentary subscription to MyHeritage, and gave received other material consideration in past years. I uploaded my autosomal DNA raw data to their DNA product. This does not affect my objective analysis of MyHeritage products.

In view of the size of your tree, I was a little surprised at the number of DNA matches and TOFR matches you have on MyHeritage. As I recall, you have about 60,000 in your tree and have 9200 matches and 11 TOFR. My tree is about 20,000 and I have almost 15,000 DNA matches and 74 TOFR. Perhaps you have a smaller tree on MyHeritage than on your main tree--Roots Magic? . . . Del
