September 9, 2017 draft tree for I-L233 "Western"

Click here to download the latest I-L233 tree.

This tree shows a new I-F25958.2 branch (part of I-A8462) and another I-Y4252* Big Y result for kit  474304. There are at least 6 Big Ys for I-L233 in progress and we expect more results very soon.

July 2017 I-L160 draft tree

We now know that CTS1758 (also known as PF4091) is an important SNP immediately below PF4088. We have found several PF4088+ CTS1758- men from Big Ys and individual testing. CTS1758 is now on the FTDNA haplotree, and it's included in the new I2a-P37.2 SNP pack at

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.
