About us


This project is dedicated to clade formation, and age analysis of the clades, as well as helping move you into your subclade in order to see who your clade-mate families are, and where they’re from.


Attention Big Y-500/700 testers: Under “Big Y-500/700” on your FTDNA personal page, the “Named Variants” file is a file of all variants on the FTDNA tree.

The “Private Variants” file is really a file of all variants that are NOT on the FTDNA tree, whether they are shared (but in a troublesome area such as the 20 million range repeat region, so not placed on the tree) or singletons down your personal line of descent. Many have been named, although the name does not appear in the Private Variant list. FTDNA has arranged them in the file by “Build 38” position number.

The Big Y Matching file is NOT the best place to find your subclade matching clade-mates who descend from the same subclade founder that you do (that was the guy who originated the SNP mutation that you share).  The best place to find your clade-mates, no matter what test they took or where, is the R U106 Project Y-DNA Results page.  See the “DNA Results” link at upper left of this page, then under Y-DNA, select Classic Chart or Colorized.

ALL U106+ Big Y-500/700 testers, including U198+ Big Y testers, are invited to send us your Big Y VCF files for our cost-free analysis.  (But the U198s cannot join the U106 project itself.)  The VCF files can be sent via this process:  

Scroll down on your FTDNA page to Big Y Results.  Click on that, then look to the far right, and click on the blue Download Raw Data button.  Then, in the pop-up window, towards the left, click on the green Download VCF button.  Then upload the zipped file, as it is, to the “Y-DNA Data Warehouse” :  https://ydna-warehouse.org/instructions.html

Joining this effort will help us research your particular clade, identifying new relationships closer to the present day. We work with other haplogroup projects, Family Tree DNA and external organizations to make your new clades known worldwide. Over 1000 of you have already participated.

General Information:

Your FTDNA haplotypes and other helpful information are located on this and the following pages.  Be sure to bookmark this page into your favorites, and check the DNA Results page for your kit from time to time, since the situation continually changes as a result of new members getting tested. Please also review the Overview and Background pages.

There is also an independent discussion forum for anyone interested in U106, but your updated data is located right here, (not there) on these pages.  The independent forum can be subscribed to via this page’s left side Links menu.  The best approach to learn about your results and Y-DNA is to review these project pages here, and the sites on the left-side Links menu.  The forum members can answer questions, especially those not specific to your particular results.

See the lower part of the Background page for information on our origins, and some interesting information about several DNA scientists and Royal families that belong to U106.

If you are a member of the R-U106 Project, but you have not tested STRs with FTDNA, then please order at least a 12 marker test, so that you can be listed on the Y-DNA Results page with your clade mates.  Otherwise, please find your haplotype listed via “DNA Results” on the left side menu, then “Y-DNA Classic Chart” at the top of that page. An explanation of the Y-DNA Classic Chart is under the "Results" tab to the right of the "Background" tab.

We strongly recommend a Big Y 700 test, because this is a “SNP Discovery” test of your Y chromosome down YOUR line of descent.  SNP Pack tests only test known SNPs selected when the SNP Packs were created, and only reach part of the way down your line of descent.


For the vast majority of Big Y 500/700 testers, there is no need to order a SNP Pack, and we don’t recommend it.



Y-DNA Results “Classic” or “Colorized" pages:

The members’ haplotype data are presented on these pages in an FTDNA-designed format, but sub-grouped by the R1b-U106 Project Administrator on the basis of your testing status.


Upon accessing these pages, use the Search feature to find your kit number.  It will only bring up your own haplotype, but it will also give you the prefix number we’re using for the long colored subgroup label above your haplotype, such as 74] including that closing bracket.  Then you can conduct a new search via Subgroup Name…contains (not exact) and that prefix with the bracket, such as 74], and it will bring up all of the kits in your area of the project, without having to scroll and scroll.


An individual member’s haplotype is reported on these pages as far down his branch as possible, according to whatever subclade he has tested down to, without testing positive for any lower currently-known subclade on the branch.  The idea here is to group you with your clade-mates, so that you can see who they are, and where they are from. Also view the peripheral and ancestral clades for further clues.


See the Overview tab above for the prefix numbers and colors for the various branches.


Members who do not have Big Y-500/700 are encouraged to order Big Y 700 so that you can actually find your subclade and your clademates.


If you have results from other testing organizations such as Full Genomes (FGC), or YSEQ, that take your position on the Y-DNA Results list down lower on your branch than what we are showing, please let the Project Administrator know.
