I Now Have 15 MyHeritageDNA Theories of Family Relativity

In response to the final refresh of the MyHeritageDNA Principle of Household Relativity in February 2021, I had 11 DNA matches with a Principle.  The Principle of Household Relativity takes my MyHeritage household tree and checks it towards different MyHeritage household bushes, and if it finds two or extra bushes with a profile for a similar individual, they create a Principle of Household Relativity.

The newest refresh on MyHeritageDNA was 4 weeks in the past – I famous it in MyHeritageDNA Updated Their “Theory of Family Relativity” Feature.

I retained the 11 Theories that I had and added 4 extra, for a complete of 15 DNA Matches that MyHeritage has discovered a standard ancestor for me and my match individual.

Right here is among the Principle matches (with figuring out info blanked):

My line is on the left, and my match’s tree is on the appropriate aspect of the dashed line.  My DNA match is my 4th cousin as soon as eliminated, with the widespread ancestors being my third great-grandparents John Wealthy and Rebecca Hill of Hilperton, Wiltshire, England.

Once I can establish every of the individuals in these Theories, and fulfill myself that the relationships are right and supported by information, I enter them into my RootsMagic software program program and create a customized DNA Match Truth with a word that reads like this:

“[DNA match name] is a MyHeritageDNA match with Randall Seaver, sharing 22.7 cM in 2 segments.  They’ve a Principle of Household Relativity, and are 4th cousins 1x eliminated with widespread ancestors of third great-grandparents John Wealthy and Rebecca Hill.”  

I then add the DNA Match to Teams in RootsMagic – on this case to the “MyHeritageDNA Matches” group and to the “John Wealthy 1789 Descendants” group.  

Whereas I’ve 10,074 MyHeritageDNA matches proper now, I’ve solely the 15 Principle matches with a recognized widespread ancestor.  I’ve recognized recognized widespread ancestors of those 15 matches, and a number of other different MyHeritageDNA matches, and have entered the shared DNA segments to DNA Painter.

Fifteen out of 10,074 is a extremely small quantity — 0.149%.  Why aren’t there extra?  It is fairly easy —  many MyHeritageDNA customers would not have a household tree on MyHeritage, and lots of who do have a tree have only a few profiles within the tree.  Wanting on the MyHeritage statistics, they’ve 75.6 million members (some with a couple of tree) and over 4,718 million tree entries.  That averages out to 62.4 tree entries per member.  

I encourage each MyHeritage member to place up a small tree (ancestors solely?) to their website to assist establish widespread ancestors with their DNA matches.  Small bushes are free on MyHeritage with lower than 250 profiles – that is sufficient to get virtually all of ancestors again to fifth great-grandparents within the small tree.  In fact, not each member is a genealogist that may return that far, however simply including your self, mother and father and grandparents and great-grandparents (15 profiles) if they’re recognized could be an ideal assist to all MyHeritage DNA matches.  


Disclosure: I obtain a complimentary subscription to MyHeritage, and gave acquired different materials consideration in previous years. I uploaded my autosomal DNA uncooked information to their DNA product. This doesn’t have an effect on my goal evaluation of MyHeritage merchandise.
