My Heritage - Theory of Family Relativity #general


rv Kaplan
 

Has anyone had any luck with this facility on My Heritage?  MH says:
 
Family Theories of Relativity will be generated between you and a match based off of common information in your family trees. The more information you add to your tree, whether it be manually added or confirming accurate matches, can trigger future theories.  
 
I have over 14,000 DNA matches on MH, and over 2,200 people on my family trees, but not a single match has ever activated the Theory of Family Relativity.
 
I asked MH Support about this and they said:
 
'As there are no theories there at this time, it simply means none have been generated based off of the information currently in your tree and the trees of your DNA matches. The information in your tree is the only information at your disposal to add to or edit that can trigger a theory.
 
This is why I would recommend continuing to build on your tree in any way possible, as any piece of information can trigger a theory. Note that it would also be imperative for your DNA matches to be working on their own trees for theories to be generated.
 
For some more information on the feature itself, theories always begin in your tree and end in the family tree of your DNA Match. The traversal of the path may include other family trees on MyHeritage, Geni, FamilySearch or historical records on the tree.'
 
Doesn't make much sense to me.  14,000 people out there matching my dna and not even my 2 closest dna matches, who I know are my 2nd cousin once removed and my 3rd cousin, attract the Theory.  
 
Am I missing something?

I had some luck with it when it first came out. Haven’t looked at it in months. I probably should.

Where on MH is the theory of family relativity? Are you referring to the Estimated relationships?

I have also never had any luck with Theory of Family Relativity and have a large number DNA matches.

It's called the Theory of Family Relativity and was brought in with great fanfare a couple of 
years ago.

I think the issue is that our matches do not have trees on MyHeritage so there is no frame of reference or starting point.
 
I don't have any matches in Relativity.  When I look at the match page, there is no tree or only a very small one.

I can understand that would cut the number of Relativity matches down, but out of over 14,000 matches, not a single one hasTheory of Relativity?   Makes me wonder.

In my experience My Heritage’s  “Theory of Relativity” is weak and of not much use. 23 and Me’s “Predicted Family Tree” is deeply flawed and dangerously misleading, whilst Ancestry’s “Thrulines” produces incredible results and has led me to make important discoveries. All depend on the size and quality of the your family tree but I have used the same tree for all three firms.

 

“Theory of Relativity” only produced a couple of results for me and they were ones where the family connection is very strong and very obvious. “Predicted Family Tree” is limited by the fact that 23 and Me is not primarily a genealogy product. But it seems incapable of distinguishing paternal from maternal predicted connections yet it presents its predictions as very definite discoveries. Then if the user does not remove their “predictions” they are, after a while, taken and set in stone in the list of user matches. I was initially reluctant to delete their predictions that didn’t show people I could identify in case I later discover who they are but then it makes it look as if I have accepted their predictions as true. Some degree of manipulation of their prediction can be done by the user but it cannot, for example, accept marriages of cousins which further limits is accuracy.  I have discussed these issues with 23 and Me and they have not disagreed with my observations and promised improvements.

 

I have had amazing and significant results with Thrulines with near perfect accuracy in it producing a chart showing how I am connected to a DNA match. It has produced results from matches where the amount of common DNA is very low. I think it is all down to the way its processors analyse individual’s trees and find common information. The only instances where Thrulines has not shown perfect results is where other uses have inaccuracies in their trees. But it is a good way to be able to graphically point out to another user they have an error. There may well be situations where Thrulines might produce inaccurate information but I have not yet encountered them.

The only reason I signed up for MyHeritage several years ago was the marketing hype about their new Theory of Family Relativity.   I waited and waited and finally after a year or two I was notified about one Theory of Family Relativity generated by their super-duper algorithm.  It said I might be related to a third cousin I had known about for years and had myself posted to my tree on MyHeritage at least a year before their algorithm discovered her.  I haven't received another Theory from MyHeritage since.   
They talk a good game at MyHeritage about the wondrous things their computers can do with their vast data, but for me at least they perpetually underdeliver.

I am not familiar with My Heritage's product, but it definitely sounds inferior to Ancestry's Thrulines.
I have to admit that I have a very large tree, and Thrulines will both try to make connections via "paper" genealogy (tree and documents) and separately or in conjunction with DNA. Thrulines helped me discover a number of new relatives. A number of the odd matches with both Thrulines and 23andme's product ended up being unknown (at the time) half siblings (always via common fathers) to known cousins.

I believe that it is the same as Ancestry thru -lines.  It is just named something else.  If your tree is not large enough or there are no matching trees then there are no theories of relativity, and no Ancestry thrulines matches.

I have 18 matches with the theory out of which only one is wrong.

I just got my 1st Theory of Relativity, among 4 kits I administer, on my 2nd cousin's non-Jewish German line.
And it seems plausible; awaiting replies from owners of other 2 trees involved.

My 2nd cousin's tree brick walled with his GGF's parents info, no siblings. The Theory found a tree owned by someone in Germany, with same parents info with a sibling, went down a generation or 2, then connected with a tree owned by someone in USA who is directly related to spouse but continued the line I was following to the (private) father of the DNA match, where it connected to extremely small & private tree of DNA match.  

Perhaps the difference in number of results between Ancestry Thrulines & MyHeritage Theory of Relativity is driven by database sizes of 18M for Ancestry & 4M for MyHeritage?

Ancestry's Thru-Lines is just matching family trees, yours and somebody else's. I have found cousins by DNA (that I knew were cousins), but they hadn't entered enough family tree to be found by Thru-Lines. But the Thru-Lines found me a second family of a cousin, that was, I think, excommunicated from the family.

If that is all that MyHeritage Theory of Relativity is, it sounds much better than it is.

I have had a few hits with the Theory of Family Relativity on MH and some appeared to be correct.  On the other hand I have had many hits on ThruLines on Ancestry.  Partly it depends on the depth of your posted family tree.  By now I have nearly 10K people in my family tree, including many people at my generation, 4th, 5th... cousins.  The fuller you make your own tree, the more likely you are to get hits.  Both Ancestry and MH have done a good job but Ancestry has many more customers and so more chances to find matches.  But I have to admit that I am having trouble at the moment with Ancestry and ThruLines because I have listed adopted-parents for my husband's grandmother whose parents died when she was 16.  Ancestry has included these adopted parents in Thru-Lines as blood relatives and I can't figure out how to get rid of them.  They came from a seemingly prolific London Sephardic family (though they, themselves, never had children) and so many of their relatives are shown as my husbands relatives at the level of 8 cM, which is meaningless.
