Click here to download our 2019-09-29 draft tree for I-Y12072
This update shows a new branch called I-Y102853, it's the 10th named branch for I-A13665 (the Driscoll family from County Cork, Ireland)
This update also shows many new SNPs in red, these were discovered recently thanks to Big Y-700 results.
Our recent draft trees have shown Y91501 immediately below PF4135. But the position of Y91501 should now be considered uncertain. Kits 667572 and 261782 have no reads for Y91501 in their new Big Y-700 results.

A third branch of I-PF4088: 2019-09-28 tree for I-L160
Click here to download our 2019-09-28 draft tree for I-L160
This tree shows a new branch called I-Y137889, it's one of three branches below I-PF4088.
I-Y137889 is uncommon, the known members have Spanish ancestry, or they are Americans with likely British ancestry. They all share some distinctive marker values: DYS447=20 or lower, and DYS425=10.
The other two branches of I-PF4088 are called I-A17273 and I-CTS1758. For reasons of legibility, we have created a new draft tree specific to I-A17273 (click here) I-CTS1758 is a very large group and it contains I-Z102, I-PF4189 and many other branches.

For reasons of legibility, we have created a new draft tree for I-A17273.
The I-A17273 branch is large and has many subbranches, it's found in Iberia but also found in Switzerland, the UK, Ireland and Germany, and even in northern Poland, Sweden, and Finland. I-A17273 was completely unknown before Big Y testing, and there is still much to learn about this haplogroup.

FT10545 unites two haplogroups below I-Y3106: 2019-09-24 tree for I-Y4460
Click here to download our 2019-09-24 draft tree for I-Y4460
On our 2019-08-20 draft tree for I-Y4460, we added a new branch below I-Y3106 (click here). The new branch was called I-FT9301 and it contained three samples. All three samples were FT9301+ and FT10545+.
After some new Big Y-700 results, FT9301 is still found only in these three samples. But FT10545 is found in a wider group: the I-Y91535 haplogroup is also FT10545+.
This updated tree shows I-FT10545 immediately below I-Y3106 (and I-Y3106 is also known as I-B57 because Y3106 and B57 are currently phylogenetically equivalent). And I-FT10545 is the parent of I-Y91535 and I-FT9301.
There are several additional branches of I-Y3106, and at least one member of each branch has FT10545- results. (These branches are I-FT78951, I-Y3118, I-S8201, I-A6106 and I-Y47356)
Note: FT10545 is well sampled in Big Y-700 tests and some Big Y-500 tests contain a few reads of FT10545. As shown on our draft tree, FT10545 occurs at ChrY position (Hg38):17349392 G to A. FTDNA's Big Y Results page doesn't currently display information for FT10545. To see your result for FT10545, change the Derived? box to "Show All" and enter YP1222 in the SNP name box (YP1222 is a neighboring SNP). When you see YP1222 displayed as a search result, click on YP1222 and you will see FTDNA's chromosome browser which shows the FT10545 position.
********
Our tree continues to show Y3106 and B57 as equivalent SNPs. We know 4 Big Y-500 results for the I-S8201 branch, none of them have B57 result. We are not aware of any individual B57 test in the I-S8201 haplogroup. There is a Big Y-700 test in progress for someone in I-S8201, maybe this will show a B57 result.

Our first draft tree specific to Isles-C: 2019-09-20 tree for I-Y5455
Click here to download our 2019-09-20 tree for I-Y5455
For reasons of legibility, we have created a new tree specifically for the I-Y5455 haplogroup. This contains all of the branches that are sometimes nicknamed Isles-C.
Isles-C was identified more than 13 years ago by haplogroup I expert Ken Nordvedt. Everyone in Ken's Isles-C cluster shares several distinctive STR marker values. And we now know that everyone in I-Y5455 also shares these values.
YFull estimates that the common ancestor of I-Y5455 lived approximately 2100 years ago. As far as we know, everyone in I-Y5455 has paternal ancestry from Ireland, especially from central-western Ireland (counties Mayo, Galway, Roscommon, Meath, Westmeath etc). There are some American families with unknown Irish/British ancestry who belong to I-Y5455. One of these families is named Armstrong which is a famous surname from the Scottish-English border area, and many of these Armstrongs settled in Ireland hundreds of years ago. But Armstrong is also often an anglicization of Irish language names that are also anglicized as Traynor, Lavery or Lowry. See https://johngrenham.com/

A Big Y for an Irish/Norwegian cluster: 2019-09-15 tree for I-Y11222
Click here to download our 2019-09-15 tree for I-Y11222
I-M26 has two major branches, I-L160 and I-Y11222, and there are also some I-M26 men who don't belong to either branch.
I-L160 and I-Y11222 are both found throughout Western Europe: Iberia, France, Sardinia, the UK and Ireland, Germany etc. But I-L160 is much more common than I-Y11222. And maybe more of I-L160's population is found in southwestern Europe, and maybe I-Y11222 has a larger percentage of its members in northwestern Europe.
There is a STR marker cluster that contains three known families: two live in western Norway, one is Norwegian-American and one is Irish-American from County Limerick (Limerick City was founded by the Vikings, as were all Irish cities).
Based on the STR variance, maybe the common ancestor of these families lived approximately 1000 years ago. Was the founder of this lineage from Ireland, from Norway, or from somewhere else? I-M26 is quite typical of Ireland but unknown in Norway other than this cluster.
*********************
This update shows a Big Y-700 result for the Irish member of this cluster. He is in a branch with a previous Big Y-500 for an Irish-American man who doesn't match the cluster well, and their common ancestor must have lived over 2,000 years ago (it's difficult to calculate MRCAs when comparing Big Y-500 and Big Y-700). Our tree calls their branch I-Y45216, maybe YFull and FTDNA will choose different names.
Both I-Y45216 men have the distinctive STR marker value DYS413=19-20. (Most of men in I-M26 have DYS413=21-21 or 21-22). The small I-Y45216 branch has a much larger parallel branch named I-A14285 usually has DYS413=19-22. So the common ancestor of these branches probably had a low value at this marker: 19-20, 19-21, 19-22, 20-21 etc.
I-A14285 is most common in Great Britain but after we had found more than 20 British families in this branch, we began to find a few from France, Spain, etc. Sometimes we think a branch is restricted to Britain and Ireland, but eventually we find continental members.
************
This update also shows a new big Y for Y15580. The I-Y15580 branch has a MRCA who lived 3900 years ago, according to YFull's calculation. All known members of I-Y15580 are Irish and British, mostly Irish. But it's a rare branch, and maybe eventually we will find continental members.

Are these men from the same family? Updated I-FGC56815 tree
Click here to download our 2019-09-12 draft tree for I-FGC56815
This tree shows a third Big Y sample for I-Y105479. Two of the three samples have similar surnames, and maybe they are from the same family and use variant spellings of the original surname. One of the samples is the I-Y105479* sample already on the tree, and the other sample is the new Y105479+ FT100258+ sample (indicated in red).
But the two men only share three SNPs below FGC56815: Y105479 and two others.
Maybe it's just a coincidence that the two men have similar surnames, or maybe the family is many hundreds of years old. There are some other men with similar surnames in this group, and when they do Big Y tests, maybe we will be able to answer the question.
All known men in I-FGC56815 have paternal ancestry from England, and I-FGC56815 is part of the I-L233 "Western" haplogroup which is rare but typical of England and the UK.
