April 3, 2019 tree for I-Y4460 (belated post)

Click here to download our 2019-04-03 tree for I-Y4460

We updated this draft tree on April 3rd, but I neglected to post it.

This tree shows several updates:

  • a second I-Y4460* result. The two men have ancestry from Syria and Ukraine.
  • a seventh I-Y3118* result, for an American with likely Hungarian ancestry
  • a new I-BY80448 haplogroup which is below I-A21812
  • a new I-Y11624 haplogroup which is below I-Y10622
  • Two I-Y3118 men share a single variant that was reported in their Big Y-700 tests. Some I-Y3118 men have ancestral results for this SNP. Maybe this is a new branch below I-Y3118, but it needs further verification
  • a new I-Y39232 branch, the two members are known cousins

Several more Big Ys for the Lindsay family, and a new branch: 2019-04-24 tree for I-A8462

Click here to download our 2019-04-24 tree for I-A8462

This tree shows 5 new Big Y-700 results for the large Lindsay family, and a new branch called I-BY58390.

Note: we updated this tree a few hours after the original post. The most current tree is dated 2019-04-24, it shows the BY58390 SNP as equivalent to Y138968

Another Big Y for the DYS413=19-22 cluster: 2019-04-22 tree for I-Y11222

Click here to download our 2019-04-22 tree for I-Y11222

This tree shows a new Big Y-700 result for one of the largest clusters within I-Y11222. This cluster is characterized by the distinctive marker value DYS413=19-22. Most of the known members are from Great Britain, but a few are from continental Europe.

YFull estimates that the MRCA of this cluster lived approximately 3400 years ago. The cluster is currently called I-BY37467 at YFull, and it's called I-Y62258 at FTDNA.

The three previous Big Y-500 results are BY37467+ but the new Big Y-700 result is BY37467-.  FTDNA has updated its haplotree to show this new branch, and YFull will update its haplotree soon. There is another Big Y in progress for this cluster.

More PF4088+ CTS11338- branches: 2019-04-18 tree for I-L160

Click here to download our 2019-04-18 tree for I-L160

This tree shows two new branches, they are both part of the PF4088+ CTS11338- set of branches. This part of the I-M26 tree was poorly known before the advent of Big Y testing.

One of the new branches is I-A24294, it's part of I-CTS11851 which has had a big expansion in the last ~2000 years. The two members of I-A24294 are from Brazil and Colombia (the Colombian man was part of the 1000 Genomes Project).

The other branch is I-BY130413*. Thanks to a recent Big Y for an American man (Irish or British ancestry?), we know that BY130413 is older than several other SNPs that were formerly considered equivalent: A19300,  BY37328 etc. The A19300+ men have ancestry from Germany.

A new branch in Disles: 2019-04-17 tree for I-L621

Click here to download our 2019-04-17 tree for I-L621

This tree shows a new branch called I-Y85772, it's part of what we nickname "Disles".

Disles includes all of the L621+ but CTS10228- branches, and "Dinaric" includes all of the L621+ and CTS10228+ branches. The name Disles comes from D for Dinaric and Isles for the British Isles. Many of the Disles branches are especially common in Britain and Ireland.

The Y67 marker pattern for Dinaric and Disles is similar but only Dinaric has the very distinctive value DYS565=9. The Disles branches all have DYS565=11 which is typical for all of I-P37.

Each branch of Disles has its own distinctive marker pattern and we can predict that some other people belong to these branches, even if they haven't done SNP testing. At the present time, all known Disles men can be placed in one of the branches on this I-L621 tree based on the pattern of their Y67 markers.

The new I-Y85772 branch contains two families, one from southwestern Germany and one from Sweden. They are not closely related, probably their common ancestor lived more than 2000 years ago.

The I-A17060 branch contains a few families from Britain and one American family which claims southwest German ancestry. This branch is called I-BY37319 at FTDNA and I-Y45825 at YFull.

The I-CTS10936* branch contains only one known family, they are American and believe their ancestor was from Germany or Luxembourg, or an adjacent area.

The I-Y50479 branch contains two families, one from southern Poland and one is American with ancestors from southwestern Germany. This branch is called I-Y44771 at FTDNA and I-Y44940 at YFull.

The I-FGC20479 branch contains 50-100 known families, all from Great Britain and Ireland. There are many known subbranches. Many of these branches are especially typical of the northern part of Ireland and Scotland.

FT14506 may be an important SNP below PH908: 2019-04-03 tree for I-PH908

Click here to download our 2019-04-03 tree for I-PH908

At the present time, I-PH908 has approximately 28 immediate subbranches, 12 branches are named and 16 are called I-PH908*. This is approximately equivalent to one man who had 28 surviving sons, and each of these sons founded a male line that has survived until the present day.

But the Big Y-500 test does not have high enough resolution to detect SNPs that occurred at each generation. It's more likely that the founder of PH908 had fewer sons with surviving male lines, and that some of these 28 lineages are from expansions in the second, third or fourth generation after the most recent common ancestor of I-PH908.

The Big Y-700 test sequences more regions of the Y chromosome, and maybe we will find some SNPs that can help resolve the 28 branches into a tree with more structure. One possible new SNP is called FT14506.

Some I-PH908 men have FT14506+ results, and others have FT14506- results as indicated on this updated tree.

At this point, the men with FT14506+ results all have the STR marker value DYS561=16, as mentioned in previous posts (click here), DYS561 seems to divide I-PH908 into two groups.

But not all men with DYS561=16 are FT14506+, there is one I-PH908* man with DYS561=16 who is FT14506- (this FT14506 result isn't shown on the tree).

People in several different branches of I-PH908 are testing FT14506 at YSeq.net and we will learn more soon.

This tree also shows three new branches, indicated in red
