A Latin-American branch in Isles-B: July 18, 2018 tree for I-S2703

Click here to download our July 17, 2018 tree for I-S2703

This tree shows a new I-Y140515* branch, based on a single Big Y for a man with Mexican paternal ancestry. He is a distant STR marker match to a man from Chile.

This tree also shows a more specific I-S2624 branch which contains two Big Ys for an American family that is supposed to have ancestry from England in the 1600s. This branch also contains someone in the Public Genomes Project, that's why many of these SNPs were given S series SNP names many years ago. Click here for my earlier post with more details.

The Mexican man has 18 private variants that weren't found in the I-S2624 Big Ys (these variants aren't shown on the tree).  Based on this number, we would estimate that the common ancestor of I-Y140515 lived a little more than 2000 years ago. But the I-S2624 Big Ys share 35 variants that weren't found in the Mexican man's Big Y. This points to a more ancient common ancestor of I-Y1450515. The Y111 markers for the two groups are very different, so maybe the common ancestor lived several thousand years ago.

A new branch in Disles: July 17, 2018 tree for I-L621

Click here to download our July 17, 2018 tree for I-L621

This I-L621 tree shows the Disles branches: the branches that are L621+ but CTS10228-. There are many different Disles branches, and I am sure we will continue to find more branches. Some branches are found only in Great Britain and Ireland, and some have been found only in continental Europe (Germany, Poland and Sweden).

This update shows a new branch called I-Y50479, it is part of I-CTS4002. The two known members have paternal ancestry from Germany and southern Poland. Their common ancestor lived more than 2000 years ago.

This new I-Y50479  Big Y was funded from our General Fund, which comes from donations from other I-P37 Project members.

This update also shows more details about the SNPs in the I-A17060 branch.

Here is a summary of the known Disles branches:

L621+ A17060+ (CTS10936-): a small group, all known members have ancestry from Britain/Ireland
L621+ CTS10936+ CTS4002-: one Big Y result for a man with western German ancestry, and probably a Swedish family that hasn't done SNP testing
L621+ CTS10936+ CTS4002+ Y50479+: one man with ancestry from Germany, one man from southern Poland
L621 CTS10936+ CTS4002+ FGC20479+: a large group, all known members have ancestry from Britain/Ireland

Almost all known Disles men have ancestry from Britain or Ireland, and they can be placed in I-A17060 or I-FGC20479  based on their Y-DNA STR marker values. There are only a handful of continental European men who are known to belong to Disles, and most of them are listed above. There is one German-American man who is currently doing SNP testing to determine his branch.

More details about the I-Z27025 branch: updated I-L160 tree

Click here to see our July 15, 2018 tree for I-L160

Our I-L160 tree became too large and we moved the more specific I-CTS11338 branch to a tree of its own, click here for more information.

This update shows additional SNP information for the I-CTS11338 branch.

This update gives more details about the I-Z27025 branch. It contains 5 men with recent Sardinian ancestry, four of these are anonymous samples from the Francalacci (2013) study, and one is a member of our FTDNA project. This branch also contains three American families: one believes he has Irish ancestry. A second family is a distant STR match and has ancestry from Belgium. The third family is more distantly related, it contains several members and is probably English origin.

The three American families share distinctive STR marker values with our Sardinian project member, so we expected that this was one of the small Sardinian I-M26 branches in Francalacci's study, and we sponsored a Big Y for one of our American members with our General Fund money.

The American shares 11 SNPs with Francalacci's samples 315-318. Very likely the other two American families share all of these SNPs. Our Sardinian project member very likely shares all of these, and maybe he shares additional SNPs with some or all of samples 315-318.

Our American project member has 37 private SNPs that weren't found in the Sardinian samples, so any common ancestor with the Sardinian men would have lived more than 4000 years ago.

A new tree for I-CTS11338/PF4091 (part of I-M26 and I-L160)

Click here to see our first draft tree for I-CTS11338

Our I-L160 tree became too large to fit on one page, so we create a new tree for the more specific I-CTS11338 branch.

For many years I-CTS11338 was much better known than any other part of I-M26. There are two known branches of I-CTS11338: the I-CTS787 branch includes the large I-Z102 haplogroup which is young and usually found in Iberia and France. Some I-Z102 samples were included in the 1000 Genomes project, and some SNPs from these samples were added to the Genographic 2.0 test (original version).

I-CTS787 has not been found in Sardinia, and its overwhelmingly Spanish, Portuguese and French. There are a few I-CTS787 members who were born in England with clear English ancestry, and some Americans with likely German ancestry. This tree shows a new branch for an American family with likely English ancestry.

The second major branch of I-CTS11338 is called I-PF4189. This branch is well known because approximately 75% of I-M26 men in Sardinia belong to I-PF4189, and Francalacci (2013) sequenced the Y chromosomes of approximately 346 men in I-PF4189. Some SNPs from these samples were included added to the Genographic 2.0 test (original version).

There are three known branches of I-PF4189. Two of these branches are known only from Great Britain: I-A19487 and I-A12373. This tree shows new information about both of these branches.

The third branch of I-PF4189 is called I-PF4190 and it includes the 346 men from Sardinia, and some other men who have mostly western German origin. There is only one Big Y sample on this tree for I-PF4190, but we have many project members who belong to this branch, many have recent Sardinian ancestry, others have German ancestry, and other are American of unknown origin.

At this point we haven't found I-PF4189 men from Spain or Portugal. It's interesting that the men who are most closely related to the 346 men living in Sardinia are men from Germany, but their common ancestor lived thousands of years ago.

two families do additional Big Ys: July 15, 2018 tree for I-L233

Click here to download our 15 July 2018 draft tree for I-L233 "Western"

This tree shows a new I-BY68045 branch. The two men in this branch are American and they have 1800s ancestry from Alsace-Lorraine, they are close cousins. This branch is part of the I-A417 haplogroup which has no known representatives from Britain. The other 3 known families in I-A417 have Irish paternal ancestry, two of them have names that suggest continental European ancestry hundreds of years ago.

Most known branches of I-L233 have representatives from Britain, and in fact have only been found in Britain, this is probably due to much stronger sampling of British-ancestry men (The distribution of I-L233 as a whole suggests an origin for I-L233 in continental Europe)

The I-A16520 branch includes the large and old Lindsey family and some other families, all have Scottish/English origin. This update shows a new Lindsey Big Y result, he belongs to the more specific I-BY32428 branch. There are four known members of this branch, and three of the four share another SNP called BY132915. We will try to determine the fourth man's result for BY132915.

Another Greek branch in I-Y18331 (parent of I-A2512): Updated I-CTS10228 tree

Click here to download our latest tree for I-CTS10228

This tree shows a new Big Y result for a Greek ancestry man. He is Y18331+ A2512+ A10959+. He belongs to the more specific I-Y66192 branch along with two other Greek men, but he is ancestral for several SNPs that are shared by the other two men.

This tree shows the Y18331 SNP in italics (slanted letters). This is supposed to indicate that the Y18331 SNP is unsuitable for testing because it occurs in a repeat region.

This update also shows a new I-Y90421 branch indicated in red, the known members of I-Y90421 have ancestry from northeastern Europe.

A new branch in Dinaric-South: Updated I-S17250 tree

Click here to download our latest tree for I-S17250

This tree shows a new branch in Dinaric-South (I-PH908), it is called A22312 and the known I-A22312 members have paternal ancestry from Bosnia and Herzegovina and from Montenegro.

This tree also indicates that the I-PH1012 branch contains one of our project members who has Serbian ancestry, and it also contains the anonymous Serbian sample ser-21 from the P. Hallast study.

This tree also shows some other Big Y results, they are shown in red.
