Link to I-L621 tree showing major STR clusters (Updated)

Click here to see our latest draft tree for I-L621.  We have used colors to show STR marker clusters. For example, the branches belonging to Dinaric-South cluster (DYS448=19, DYS449=30 or similar, and DYS565=9) are colored blue.

We also show the many Dinaric-North branches, the Disles branches, and two small clusters within Dinaic-North: a Jewish cluster, and a Mediterranean cluster. All of these clusters can be easily identified by STR marker values.

This colorized tree is not attempting to show a geographic or ethnic/historical origin for every branch. We are only showing STR clusters. For example, there are no known STR marker values specific to the I-Y4460 branch, therefore I-Y4460 is shown as part of the bigger Dinaric-North STR cluster.

UPDATE 29 August 2016--You will notice that the tree shows that the Dinaric-South group belongs to the I-PH908 branch. PH908 is a SNP that was first reported in the Pille Hallast survey in 2014. This SNP is not covered by the Big Y test and most those who have Big Y test result have no call status for PH908. Some have one or two positive or negative reads. Two persons from DinS cluster (I-S17250* and I-Z16983 haplogroups) have positive T+ results in their YFull reports. Three persons  who have S17250+ and BY128+ results have negative C- results. Two persons from I-Y4460 and I-Z17855 haplogroups also have negative results. The position of this SNP relative to Y4882 is to be investigated.  PH908 could be a characteristic SNP for the Dinaric South cluster. The PH908 test is available at YSeq.net and we recommend it for all Dinaric-South men. Two Din-S men have already reported PH908+ results from YSeq. https://www.yseq.net/product_info.php?products_id=32650

Link to July 2016 draft tree for I-L161

Click here for the latest tree for I-L161 "Isles".

Changes since the May 2016 tree:

--sample 129783 added. He is S2742+ and is the only person in his more specific branch with Big Y results. The I-S2742 group includes Isles-B1, Isles-B4 and some smaller branches.

--sample 306862 belongs to the Isles-D3 (also called Isles-D99). He is the only person in Isles-D3/D99 to have done Big Y or similar testing. But we have learned that he shares two SNPs with five anonymous samples who did the Chromo2 test at britainsdna.com So we are now able to label his S7714+ S7708+ branch as I-S7714.

You can see that there was a very rapid expansion in the Isles-C and Isles-D groups: the ancestor of all of Isles-C and Isles-D was Y3734+ and the long list of SNPs equivalent to Y3734 represents thousands of years where there was no permanent increase in the Y3734+ population, and then almost simultaneously it split into at least four lines, all of which have survived to the present day. There are very likely some other surviving lines that diverged from the others at the sample time but no Big Ys have been completed for these lines yet (these lines are the part of Ken Nordtvedt's Isles-D1 group that doesn't fall into one of the branches already on the tree).

There are also some updates to the I-PF4135 section at the bottom of the tree (Isles-A)

Tree for I-Y11222 (a major branch of I-M26 "Sardinian")

Click here to download our first draft tree for I-Y11222.

What is I-Y11222? It's a major branch of I-M26 "Sardinian". The vast majority of men in I-M26 have the very rare value YCAII=11,21 or similar.  (YCAII is one of the 37 STR markers in the popular FTDNA.com genealogy DNA test).

75%+ of these people with 11,21 belong to the I-L160 haplogroup which is found in Sardinia, Spain, Portugal, France, Italy, Switzerland western Germany, Britain, Ireland etc. So far, the rest of these people with 11,21  belong to I-Y11222 which is found in the same places as I-L160 and which has a similar age as I-L160 (approximately 5500 years ago according to the YFull.com tree) The common ancestor of I-L160 and I-Y11222 surely also had the 11,21 value and lived approximately 8000 years ago.

Link to historical posts about I-P37 haplogroup

For many years I posted about the I-P37 haplogroup on my other blog, cullengene.blogspot.com  But eventually I started this blog and copied all the haplogroup-related posts here. At some point, all the old jpgs/image files disappeared from this blog, I don't know why.

Recently I found this site which archived the old posts from the Cullen blog:
http://cullen212.rssing.com/chan-23512892/all_p1.html

When I have time, I will try to transfer the I-P37 haplogroup tree drawings etc to this I2a blog.

(Update: I think the images disappearing has something to do with me getting an Android phone, and somehow I moved the files around)

I-S21825 draft tree

What is I-S21825? It is all of I-P37 except I-M26 and I-M423. That means I-S21825 includes the rare I-L233 "Western" branch and the much rarer I-Y11949 "Alpine", I-L1294 "France", and I-L880 "Northern France" branches

Here is a simple tree showing the major groups of I-P37
              /I-M26
     /I-CTS595
    |         \I-S21825
 I-P37
    |       /I-L621
     \I-M423
            \I-L161

Note:  P37, M26, S21825, M423, L621 and L161 each have dozens of equivalent SNPs, but CTS595 is the only known SNP at its level. Therefore I-P37 split into three branches almost simultaneously (into the I-M26, I-S21825 and I-M423 branches).

And here is the new I-S21825 draft tree:

Links to new I-L161 draft tree

Here is the new L-L161 draft tree based on Big Y results. Click here for a pdf version and click here for a png version.  (Note the PDF version was updated Feb 10, 2016 and includes some SNP names not shown on the png version)

There has been a lot of progress and I think all known I-L161 people fit into one of the major branches shown here, and in most cases we can predict a very specific branch for someone based on 67 STR markers.

Here are some comments starting at the top of the tree:
The I-Y13338 branch has very few known members, they were formerly called the Isles-B2b cluster. The I-Y13338* branch at very top is a closely related group from Thrace (the European part of Turkey and adjacent area of Bulgaria), and the I-Y13330 branch contains two members of a Polish family. Based on distinctive STR markers I think a family from southern Iraq, a family from central Germany, and a family from Cuba also belong to I-Y13338 and they all seem to be closer to the Polish family than to the Thracian group.

The I-S2742 group contains more branches that were formerly called Isles-B: for example, the Isles-B4 group which is very rare and from southern England and has the very distinctive marker value DYS388=11. I-S2742 also includes the Isles-B1 group which is all closely related to each other, maybe they are all Americans with English ancestry? And I-S2742 also includes a few additional English-origin families who don't belong to B1 or B4, as well as some German families who haven't done Big Y and haven't fully tested the known SNPs.

The I-FGC7169 group contains all of Ken Nordvedt's Isles-C and Isles-D clusters which are almost completely Irish and British with a few Canadians with ancestry from France. It turns out that Isles-C1, Isles-C2, and Isles-D2 are all related to each other and comprise the I-FGC7184 branch (although Isles-C1 is more complex and doesn't form a single branch. Isles-C2 and Isles-D2 are each single, well-defined branches). But Isles-D1 turns out to be very complicated and not closely related to Isles-D2. There are several small branches that were formerly called Isles-D1: Isles-D3/D99 represented by kit 306862, the "Todd cluster" represented by kits 192579 and 432883,  and kit 164613 is in his own branch at present.

The I-A1150 branch contains more Isles-B people: Isles-B5 which doesn't have very distinctive STR markers, and Isles-B3 which has the distinctive DYS392=12 value, and a few people who don't belong to either of these groups. All known members of I-A1150 are from Britain or Ireland (most are from England).

The branch shown with the novel variant 2720236 A to G  (now called A10028) and 19 additional novel variants is represented by only two known men, one from Scotland and one from Ireland

The I-PF4135 branch is the Isles-A branch, mostly from Britain and also Ireland. Most of the subbranches shown are based on Big Ys for the Munro family, and if more families do Big Ys we will learn much more. There is a single man, kit 23143 who has received PF4135- results and his STR markers are slightly different from the PF4135- men, but I'm sure he shares most of the other novel variants/SNPs listed as equivalent to PF4135.
