June 2017 draft tree for I-S2703 (part of I-L161 "Isles")

Click here to download our June 14, 2017 draft tree for I-S2703

I-S2703 is a major branch of I-L161 "Isles".

New in this update:
there is a second Big Y for the I-FGC8393 branch. The two men share 26 SNPs below S2742, but each has approximately 10 unique novel variants, meaning that their common ancestor probably lived more than 100 years ago. Their 111 Y-DNA STR markers are also quite different. They have ordered their YFull analysis and they should be shown in a final position on the YFull v5.06 tree, which will be released approximately 2 months from now.

The tree shows more SNPs highlighted in yellow, these SNPs are available at FTDNA

July 1, 2017 I-L233 draft tree

Two more Big Ys have been completed for I-L233. One of them shares a single novel variant with an earlier Big Y, and we now know a new branch of I-Y4252 called I-FGC56815. The FGC means Full Genomes Corp, and maybe someone from this branch has done a YElite test at Full Genomes Corp, or someone purchased a BAM analysis from FGC, or maybe FGC analyzed a public genome that belongs to this branch.

The second Big Y result doesn't share any novel variants below L233  and Y4252 with anyone else, except. We now know 6 named branches below I-Y452, and there are also seven unnamed branches that each contain only a single family at present. I-Y4252 contains thirteen known branches at this point, it had a very rapid expansion.

New I2a-P37.2 panel at

For several years has offered a very good I2a-M423 panel which covers almost every important SNP for I-L621, I-CTS10228 Dinaric, Disles, and I-L161 Isles. Today YSeq introduced a SNP panel that is for the I-M26 "Sardinian" branch, the I-L233 "Western" branch and the smaller branches like Alpine, Northern France, France etc. Here is the link: Of course, many members of the I-P37 project have already done Big Y tests, or extensive SNP testing and you don't need any new tests. But I recommend this SNP panel for many people in I-M26 "Sardinian" and I-L233 "Western". It's much more complete than the I2-P37 SNP pack at FTDNA. It's also cheaper ($88) but you will need to give a new cheek scrape DNA sample (there is a $5 kit fee) and you will not be able to add your YSeq results to your FTDNA page. 

I can also recommend this test to I-P37 men who have done tests at other companies and don't wish to order tests at FTDNA for whatever reason.

June 8, 2017 Draft tree for I-L621

Click here to download the June 8, 2017 draft tree for I-L621

There are several interesting additions:

--Disles-A: Almost all I-L621 men are CTS10936+. There are a few families that are L621+ CTS10936-, and we call this branch Disles-A. The D means that it is very distantly related to the Dinaric branch, and the isles means that this branch is typical of the British Isles. We now have a second Big Y result for Disles-A, and we can now call this branch I-A17060

--Disles-B: we have discovered a man who is CTS10936+ but CTS4002- and these SNPs (and several others) are no longer equivalent. The man had only 37 STR markers, and we predicted that he belonged to the I-CTS10228 "Dinaric-North" group, but this prediction was incorrect.  He is an American with paternal ancestry from southwestern Germany. With 67 markers it's very easy to distinguish Dinaric (L621+ CTS10228+) from Disles (L621+ CTS10228-) because Dinaric has the very distinctive value DYS565=9

-Disles-B:  thanks to a new Big Y, we now have 17 SNPs which define the I-A16633 branch. I think most of the Disles men from Britain and Ireland will belong to this branch, but some of them may not share all of the 17 SNPs. The I-FGC20473 branch is much smaller

--I-CTS10228*: There are four known branches of the I-CTS10228 Dinaric branch, and for many years there was only one known man who was CTS10228+ but who didn't belong to any of the branches, this man has paternal ancestry from southeastern Poland. Now there is a second CTS10228+ A2512- Y4460- Z17855- S17250-, this man has paternal ancestry from Alsace (southwestern Germany/France border area, now part of France). The Polish-ancestry and Alsatian-ancestry man don't share any unique novel variants/SNPs. There are many SNPs listed as equivalent to CTS10228, and it's possible that the Alsatian-ancestry man is ancestral (negative) for some of these, he has submitted his BAM file to YFull and we will learn the answer soon. Like all other I-CTS10228 men, the Alsatian-ancestry man has the distinctive marker value DYS565=9
