New I-FT303300 branch: 2020-06-29 tree for I-Y3118

Click here to download our 2020-06-29 draft tree for I-Y3118


This tree shows a new branch called I-FT303300, there are two known samples, they both have Russian paternal ancestry.

This update also shows some new samples in existing branches.

Our tree shows I-Y25010 below I-FT40113. This is based on FTDNA's haplotree/Big Y Block tree. There are two known I-Y25010 samples, one of them is a member of the I-P37 project, he did a Big Y-500 which didn't cover the FT40113 position. The other  I-Y25010 sample isn't a member of the I-P37 project and he has no result displayed for FT40113, but maybe FTDNA found a few positive reads.

A new branch in I-A16681: 2020-06-26 tree for I-S17250

Click here to download our 2020-06-26 draft tree for I-S17250


This update shows a new branch called I-Y160614, it's part of the I-A16681 haplogroup and much larger I-BY128 haplogroup. The two I-Y160614 samples have paternal ancestry from Hungary and Russia.

This update also shows a new I-A16681* sample and a new I-A14973* sample.

New branches in Isles-C2 and Isles-C3: 2020-06-21 tree for I-Y5455

Click here to download our 2020-06-21 draft tree for I-Y5455 (Isles-C)

This tree shows two new branches and additional SNP information in other branches.

A new branch in I-S7708 (Isles-D3): 2020-06-21 tree for I-Y3723

Click here to download our 2020-06-21 draft tree for I-Y3723


This update shows a new branch in I-S7708 (Isles-D3), and it shows many additional FT series SNPs that are equivalent to S7708.

Our first tree specific to I-Y4665 (Isles-D2): 2020-06-21

Click here to download our first draft tree specific to I-Y4665 (Isles-D2) dated 2020-06-21

For reasons of space we have created a new tree for I-Y4665. We can now show much more SNP information.

This update shows two new branches, both part of I-A10741.

Membership in I-Y4665 can often be predicted with only Y12 STR markers. Almost all I-Y4665 men have paternal ancestry from Ireland, and some are maybe from Scotland. But we recently found a man with ancestry from central Poland who almost certainly belongs to I-Y4665

Another sample in the English I-BY175050 branch: 2020-06-19 tree for I-F1295

Click here to download our 2020-06-19 tree for I-F1295

I-BY175050 is a major haplogroup: YFull calls it I-BY174945 and calculates that it was formed 5800 years ago and had a MRCA 4600 years ago.

This update shows a 4th sample for I-BY175050. All of these samples have English ancestry but maybe this will change with more testing.

This update also shows some new phyloequivalent SNPs in other branches.

Many updates for rare "France" "Northern France" and "Alpine" branches: 2020-06-15 tree for I-S21825

Click here to download our 2020-06-15 draft tree for I-S21825

I-S21825 is one of the major branches of I-P37, but I-S21825 isn't very common. I-S21825 contains the I-L233 "Western" branch, and some other branches that are much rarer:


  • I-L1294 which was formerly nicknamed I-P37.2* "France", this group has the distinctive marker value DYS388=9. This group is found in Spain, France, Great Britain and western Germany. This group is easily recognized by STR markers, and scientific studies have found several examples, click here to find our previous I-L1294 tree with more information. But I can find only two I-L1294 men at FTDNA who have recent continental European ancestry: one lives in northern Spain and one lives in northwestern Germany, neither is a member of the I-P37 project at FTDNA.
  • I-L880 which is nicknamed "Northern France", there are two Big Y samples, one with French ancestry and one with northwestern German ancestry. According to YFull's calculation, the MRCA of these two samples lived approximately 6000 years ago. FTDNA recently added new information to their haplotree, and we include it on this draft tree: some people are Y28222+ but L880-, these SNPs were formerly considered equivalent. I don't know what samples FTDNA used to create this I-Y2822* branch, maybe a scientific sample?
  • I-A8689 is nicknamed "Alpine", the known samples are from southern Germany, Austria, northeastern Germany, Albania, Romania and southwestern Anatolia (Turkey). This branch has a fairly recent MRCA and it's most closely related to the larger I-L233 "Western" branch.


This I-S21825 tree contains information about all of these branches, except I-L233.
