Would this work as a plan for using Y haplogroups on WikiTree?

+10 votes

With regard to earlier discussions of using Y haplogroups in WikiTree: https://www.wikitree.com/g2g/192486/what-think-this-rough-plan-storing-using-haplogroups-wikitree

Is it possible for WikiTree to automatically link to a Y subhaplogroup if it is already at YFull.com?  For example, a Y-DNA tester enters (on their DNA Tests page) that their Y haplogroup is R-M269.  Clicking on R-M269 takes them to


There they can see where their SNP / haplogroup belongs in the hierarchy of the Y haplogroup tree.

Thanks and sincerely,

I like the idea (but then I like most of your ideas!).

However, it has clear limitations.  For one thing, it's going to create a lot of questions, like "what does that mean", "how do I do that", and "YFull doesn't have mine, what do I do".

For high level haplogroups, such as from 23&Me, Living DNA, and any of the FTDNA STR tests, it should be straightforward, should not be much disagreement in YFull.  But for those who have tested further, there's a high likelihood of disagreement between YFull and FTDNA and others.  My own goes 2 branches further than YFull, so I would have to limit this field to a higher level SNP than what I would prefer to use.  And from what I've seen, YFull is having trouble keeping up with FTDNA, so there are likely to be many with higher level YFull SNP's than on FTDNA.
good grief! I couldn't even find mine, sorry but it's a bit overwhelming. My solution is to simply do screens shots of my y tested surnames that are identified in groups at familytreedna.com. These are "public" results and as such serve to substantiate the DNA participants who do match. Simple.
Hello Sherry, If one of your Y tested surnames is (for example Smith) and his haplogroup is R-M269 and you know of another Smith whose haplogroup is R-M269 then you still don't know for sure they share a direct paternal line ancestor in a genealogical time frame whose surname was Smith. That is because the time back to the most recent direct paternal line ancestor for everyone who is R-M269 is about 6,400 years. The Smith surname is not that old.  About 110 million European men belong to haplogroup R-M269.

Are you taking screen shots of y tested surnames with their associated haplotypes or haplogroups (or something else)?

Most sincerely,

I don't have my Smith lines up, but you are welcome to see my Mitchell, Martin, and Johnson lines as I have tested and posted screen shots. Just follow those primary lines, and I have attached screen shots to all male descendants I think,,, let me know if I missed one!


specific groups as are proved matching Peter.
Plus, I am ~almost ~ ready~ to continue to post to my double Mitchell line, which will tie together the infamous Captain William Mitchell who is thoroughly written up in Maryland archives and his brother Thomas. This proof will rest on a bit of paper and a LOT of DNA evidence!
Hello Sherrie,

I like what you have done given that we no longer have YSearch and most of these anonymous Y-DNA testers are not in WikiTree.  Your work is important because it is the matching Y haplotypes of direct paternal line descendants that need to be used to "confirm" father/son relationships in direct paternal lines. That is more important and useful than Y haplogroups.

However the original question is of lesser genealogical value and has to do with how to make better use of Y haplogroups in WikiTree.

Most sincerely,
Haplotype matching does not work except as a 'predictor' of the terminal SNP and haplotree branch. STRs do not work as well as SNPs when considering true relatedness.
Hello Leake,

You said “Haplotype matching does not work except as a “predictor” of the the terminal SNP and haplotree branch”.  Please confirm you intended to write haplotype and not haplogroup.

Thanks and sincerely, Peter
Yep, that's exactly what I meant.

I like this idea.  Over time it could also be a learning feature for folks to see how the SNP world works and possibly create interest in finding their own haplogroup at a future date.

Since FTDNA and Yfull commonly use different designations for the same location, some method for showing both vendor's "equivalent SNP designation" would be necessary.

A case in point for this is that my 4th cousin's and my newly developed BigY tests and Yfull's analysis thereof use different haplogroup calls; however, deeper review shows that both vendors show the equivalent name for the other vendor's designation.

Thanks for the suggestion Peter.
