2020-05-23: Our first tree specific to I-Y3118

Click here to download our 2020-05-23 draft tree for I-Y3118

For reasons of legibility, we have created a new tree specific to I-Y3118

• I-BY37317 is a new branch immediately below I-Y3118. FTDNA added I-BY37317 to its haplotree recently, but the relevant Big Ys were completed in 2018 and 2019. Two samples: one from Montenegro and one from Syria.

This tree shows several new branches:

• I-BY37317 
• I-Y70430 is split into an I-Y70430* branch and a more specific I-Y73542 branch
• I-BY33671
• I-BY199341

For reason of legibility we will create a new tree for the large I-Y3118 branch.

some SNP blocks split thanks to Big Y-700 tests: 2020-05-20 tree for I-S17250

Click here to download our 2020-05-20 draft tree for I-S17250

I-BY142076 is a branch immediately below I-S17250. There are only three samples in I-BY142076, they have ancestry from Belarus and maybe surrounding areas: a recent Big Y-700 result (not in the I-P37 project) is BY142076+ BY177515+ but he is ancestral for Y40662 and 10 equivalent SNPs. The two members of I-Y40662 have Big Y-500 results only.

I-FT33727 is a new branch immediately below I-A815. I-FT33727 contains two closely related men (Hungarian ancestry) in the more specific I-Y83661 branch, previously they had Big Y-500 results. One of the Hungarian men upgraded to Big Y-700 and he learned that he shared two SNPs  (FT33727 and FT34568) with a Polish-ancestry man who was previously placed in an unnamed I-A815* branch.

I-A16681 contains 4 Big Y samples, one recently upgraded to Big Y-700. Two samples share an additional SNP: BY55257, and we have created a more specific I-BY55257 branch. A third sample has only Big-500 results and BY55257 wasn't sampled. A fourth sample has Big Y-700 results but he's not a member of the I-P37 project.

Lindsay family details and a comparison of YFull and FTDNA's trees: 2020-05-20 tree for I-FT11343

Click here to download our 2020-05-20 draft tree for I-FT11343

The I-FT11343 haplogroup has a common ancestor who lived approximately 1,000 years ago, and very likely he was named Lindsay. All I-FT11343 men are named Lindsay/Lindsey/Lindesay or similar, or are very likely paternally descended from Lindsay men.

This update shows a new branch called I-BY189035, it's part of I-FT97878. On our previous trees, BY189035 and FT97878 were considered to be equivalent. There are now four I-FT97878 samples, two of them belong to the more specific I-BY189035 haplogroup. All 4 men are American and their Lindsay ancestors have been in the USA since the 1700s, maybe they are all descended from the same immigrant Lindsay ancestor. YFull estimates that their common ancestor lived 400 years ago.

If you look at our tree, you will see that the I-FT97878 and I-BY189035 branches are a small, specific and recent part of I-FT11343. The Lindsay family is large and it has been expanding continuously for approximately 1000 years.

This update also shows some new SNP information for other branches, indicated in red



Click here for YFull's I-Y36039 tree which includes the I-FT113343 haplogroup, but see this note:

There are some important differences between our draft tree/FTDNA's tree and the YFull tree. This is because the YFull tree doesn't contain all the Big Y samples from FTDNA. And some of the samples at YFull are from Big Y-500 tests, in some cases men have completed an update to Big Y-700 but they haven't sent their new BAM file to YFull.

The YFull tree shows a branch called I-Y36039, and YFull shows Y36039, FT113343, A16520, A16521, A16524, Y168200, FGC48786/YP5849 as equivalent SNPs.

In fact A16520, A16521, A16524, Y168200, FGC48786/YP5849 are equivalent (and some new FT series SNPs are also equivalent), but I-Y36039 is a more specific haplogroup, and I-FT113343 is an even more specific haplogroup. You can see these details on our project's I-A8462 tree and on FTDNA's I-A8462 tree, click here for our latest post about I-A8462

When you compare the trees, this I-FT11343 draft tree and FTDNA's I-FT11343 haplotree/Big Y Block tree contain YFull's I-Y138968 branch and YFull's large I-F25958 branch. But YFull's  I-Y36040 branch is in fact FT11343- (and I-Y36040 contains no Lindsay men). Eventually people will send new BAM and VCF files to YFull, and YFull will update its tree.

A branch specific to a Scottish family in Isles-B5: 2020-05-02 tree for I-A8742

Click here to download our 2020-05-02 tree for I-A8742

This update shows a new branch called I-FT40017, it's specific to a family with paternal origin from Scotland. I-FT40017 is part of the Isles-B5 cluster (I-BY37270, also called I-BY37269). YFull estimates that the common ancestor of I-BY37269 lived approximately 4300 years ago, and at this point all known I-BY37269 men have British paternal origin.

An I-M26 cluster from Turkic Russia: 2020-04-26 tree for I-Y11222

Click here to download our 2020-04-26 draft tree for I-Y11222

This update shows a new branch called I-BY93072, it contains two Big Y samples, one has French Canadian ancestry and the other is from Republic of Bashkortostan (Bashkiria) in the Russian Federation. Their most recent common paternal ancestor lived more than 4000 years ago.

This is a very small haplogroup: there are no known men with STR markers that match the French Canadian man. And the man from Bashkortostan has only two matches, they are from the Chuvash Republic and the Republic of Tatarstan. These men have several differences in their Y37 and Y67 STR markers and their common paternal ancestor lived several hundred years ago. Bashkortostan, Tatarstan and Chuvashia are adjacent republics in the Russian Federation, and at least two of the three men trace their paternal ancestry to Turkic peoples (Bashkirs and Tatars).

In general I-M26 is very typical of Sardinia, Spain, Portugal, France and western Europe. I-M26 is almost unknown in Eastern Europe and most of Central Europe, I am aware of only these I-M26 samples:

• there is a Jewish branch from Poland, Lithuania, Russia etc, they belong to I-PF6950 
• there is an anonymous scientific sample from Greece, he also belongs to I-PF6950 but he's not closely related to the Jewish branch
• there are two samples from Bosnia and Herzegovina, they have Muslim paternal ancestry, maybe they belong to I-PF4190 which probably originated in Sardinia. It's possible that they are from the same family
• I know only one sample from Hungary/Romania, he believes he has ethnic German paternal ancestry and in fact he probably belongs to the I-Z27416 branch with some men from southwestern Germany (this branch is shown on the I-Y11222 tree linked above)
• I only know one sample from Austria and one from Bavaria, they are distantly related to each other (MRCA more than 1500 years ago?), they belong to I-BY130413 which is one of the PF4088+ CTS11338- branches
• there is one man with ethnic German paternal ancestry from Slovakia
• there is one sample from Finland, others from Poland, and Sweden, they probably all  belong to I-A19395 which is also found in Germany and Great Britain and Ireland. These Finnish, Polish and Swedish men all have ancestry from areas settled by Germans or Swedes, but it's not clear how closely these men are related to each other.
• there are a few additional I-M26 men from Germany, Poland and Sweden who probably are A19395-
• Update July 2020: there is man from Serbia with M26+ Z113+ Big Y-700 results. There is another man from western Bulgaria with Z113+ results from an individual SNP test. They aren't closely related according to their Y-STR markers. I-Z113 is the largest recent branch of I-M26, it has a MRCA who lived 1550 years ago according to YFull's calculation, and almost all known I-Z113 samples are from Spain, Portugal and France.

If you draw a line from Venice north to Rostock, Germany, I think these are the only samples I know from more easterly regions. I-M26 is very typical of western Germany and Switzerland and the list of those samples would be very long.

****************

This tree also shows a third sample in I-Y45584 (FTDNA calls this branch I-BY151272). Two of the samples have Big Y-500 results and one has Big Y-700 results, and we didn't find any downstream SNPs shared by only 2 of the 3 men. All three samples have Irish paternal ancestry

I-M26 is very typical of Ireland, I-M26 is much more common in Ireland than in Great Britain. But the I-M26 men in Ireland belong to many different branches of I-M26.  I-Y45584 and its neighbor I-S2699 are probably the largest branches of I-M26 that are found in Ireland, and we can use STR markers to predict that many other Irish-ancestry men belong to I-Y45584 and I-S2699. But many other Irish men belong to other branches of I-M26, for example the I-PF6950, I-PF4190 and I-A19395 branches mentioned above, and many other branches.

Another update for the Barclay cluster: 2020-04-21 tree for I-CTS11338

Click here to download our 2020-04-21 tree for I-CTS11338

I-BY67299 includes many men with Scottish/northern English ancestry, they are named Barclay/Barkley, Williamson, Falconer, McLaughlin, Rose, Gray etc. I-BY67299 isn't closely related to any other branch, as is shown by the large block of SNPs that are equivalent to BY67299.

There have now been six Big Ys for this branch. This I-CTS11338 draft tree now largely agrees with FTDNA's haplotree, for the I-BY67299 section at least.
