There are now _4_ Big Ys for the American Nance family, they probably share a common ancestor who lived in Virginia in the 1600s or 1700s. They share A17999, Z45269 and many other SNPs that aren't in other families. And three of the men share a single additional SNP called Z45268/Y48314, the fourth Nance man is ancestral (negative) at this position.

Click here to download our 2019-03-05 tree for I-Y11222
There are now four Big Ys for I-S2699. According to YFull's calculation based on two Big Y-500 results, the common ancestor of I-S2699 lived approximately 1200 years ago. All of the members have Irish paternal ancestry as far as can be determined,
Two new Big Y-700 tests have been completed, and we now have learned of two subbranches.

Many Big Y-700s for Driscoll family: 2019-03-03 tree for I-Y12072 (Isles-A and related branches)
Click here to download our 2019-03-03 tree for I-Y12072
Beginning in February 2019, all Big Ys completed at FTDNA are Big Y-700s, this test sequences additional regions of the Y chromosome compared to the Big Y-500 test. More novel variants and named SNPs are being reported in Big Y-700 results, but it's difficult to place many variants in the haplotree because these regions were not tested by the Big Y-500.
But the large Driscoll family (I-A13665) has already completed at least 4 Big Y-700s, and we can say that three variants from Big Y-700 are approximately equivalent to A14359 which was already known from Big Y-500 tests. And at least 4 Big Y-700s have been completed in other branches of I-Y12072 and we can say that FT3422 is approximately equivalent to PF4135.
This tree also shows a new branch called I-BY176167, it's part of I-A14359, and part of the wider I-A13665 Driscoll family.
We have added I-A9877 to the tree, it's part of I-Y12072 (the Munro family and relatives).
All of the additions are indicated in red.

7 new Big Ys, a new branch, a new STR pattern: 2019-03-03 tree for I-PH908
Click here to download our 2019-03-03 tree for I-PH908 (the Dinaric South cluster)
For a few years we have known about an important STR marker pattern in I-PH908 (Dinaric South):
Many Dinaric South men from the former Yugoslavia and adjacent areas have the marker value DYS561=16. This is the normal value for I-CTS10228 (Dinaric) as a whole. When a Dinaric South man with DYS561=16 does Big Y, it's likely that he won't share any variants below I-PH908 and his haplogroup will be I-PH908*. But as more men do Big Y, we are starting to find more shared SNPs and name more branches.
Many Dinaric South men from other areas (Central Europe, Germany etc) have the distinctive marker value DYS561=15. Men with this value are likely to belong to a large named branch of I-PH908, for example I-A356/Z16983.
Of course there is much geographic overlap and Dinaric South men with DYS561=16 are sometimes found in Germany and some Dinaric South men with DYS561=15 are found in SE Europe.
***************
Here is another important STR marker pattern:
Most Dinaric South men have DYS557=16 or 15. When we see Dinaric South men with the unusually high DYS557=17 (or even 18), they often belong to the more specific branches I-Y52621, I-Y56203 or I-BY189804. These branches are all part of the larger group with DYS561=16.
****************
This tree shows a new branch called I-BY135769, the two known members have ancestry from Poland and Russia. FTDNA hasn't added this branch to their haplotree yet. This branch has DYS561=16 and DYS557=16/15.
****************
This tree also shows several new Big Ys that belong to already-known branches, and it shows updated SNP information for many branches. All of this is indicated in red.

Another branch in Isles-B1: 2019-02-20 tree for I-Y14612
Click here to download our 2019-02-20 tree for I-Y14612
This tree shows a new branch based on a Big Y-700 result. Previously A18000, A17999, Z45269/Y51137 and approximately 4 additional SNPs were considered to be equivalent. The new result is A18000+ but ancestral (negative) for the other 6 SNPs. We now have an I-A18000 branch and a more specific I-Z45269 branch.
All of these men belong to the Isles-B1 cluster, which is poorly defined by SNPs and STRs. In my opinion, it's not important to define Isles-B1 exactly, but maybe Isles-B1 is a useful way to refer to these L161+...L1498+ S2703+ S2742+...Y14612+ branches that have similar STRs and that are found in places like England, Sweden and Germany.

First Big Y-700 results: Updated I-CTS10228 Tree
Click here to download our 2019-02-20 draft tree for I-CTS10228
FTDNA has updated the Big Y test: all tests in progress, and all future orders, will be called Big Y-700. The 700 means that more than 700 STR markers will be reported. More importantly, they will use new laboratory methods and sequence new areas of the Y chromosome, and we can expect more novel variants/SNPs to be reported.
The first five Big Y-700 results were completed this week in the I-P37 project and an additional 40 tests are in progress.
This updated I-CTS10228 tree shows two new branches:

This updated I-CTS10228 tree shows two new branches:
- the I-BY153008 branch is based on two Big Y-500 results. It's part of I-Z17855. One of the Big Y results is for a man with paternal ancestry from Serbia, and the other man's ancestry is unknown
- the I-BY99606 branch is based on one Big Y-500 result and one Big Y-700 result. It's also part of I-Z17855. FTDNA hasn't named this branch yet, there are approximately three equivalent SNPs and we don't know which name FTDNA will chose. One man has paternal ancestry from Serbia and the other man has paternal ancestry from Macedonia. The Big Y-700 result discovered 10 novel variants that weren't reported in the other man's Big Y-500 result. But probably he is also derived (positive) for most of these 10 variants, and they weren't reported because the Big Y-500 didn't sequence these parts of the Y chromosome.

What we learned about I-Y5451 (Isles-C2) in 2018
I-P37 project member Ryan Casey wrote this summary of recent discoveries about I-Y5451. This is the haplogroup that is sometime nicknamed Isles-C2, it has several distinctive STR marker values, especially DYS392=12. This branch is especially typical of central-western Ireland (counties Roscommon, Galway, Mayo etc.), and it has a MRCA who lived 1150 years ago according to YFull's estimate.

https://www.familytreedna.com/public/I2aHapGroup?iframe=ycolorized
Ryan's summary:
- 1/26/18: Y43901 is shared by two men and becomes the second known subclade of Y5451 after FGC14463.
- 2/5/18: FGC14458 separates from the Y5451 SNP block after it becomes known it’s upstream.
- 6/6/18: FGC14463 is known to have occurred before FGC14449 because a man does BY testing and is positive for the former and negative for the latter, FGC14449 appears to be the SNP that defines the Keaveney surname.
- 10/15/18: Y128131 and possible equivalent SNP Y129461 are shared between two men and becomes the third known subclade.
- 11/2/18: BY150381 and equivalent SNP Y45719 are shared between two men and becomes the fourth known subclade.
- 12/10/18: A subclade of BY150381 called BY186335 is discovered along with its 7 equivalent SNPs and is shared by two closely related men with a Spanish surname
