New I-M26 tree after 5 Big Ys for M26+ L160- people

The current FTDNA haplotree shows around 21 branches of I-M26, and 20 of these branches belong to I-L160 and everyone else is lumped together in I-M26*:
In fact, the I-P37 project has known for several years about many other branches which are M26+ L160-.

 The I-L277 * and I-L247 groups are very small. The I-PF6947 group is bigger (at least outside of Sardinia/in North America), about a third of I-M26 in Ireland might belong to I-PF6947. But by far most of the M26+ L160- people belong to what is called the I-L672* branch on the tree above. This includes the large group that Ken Nordtvedt nicknamed M26*-"France" many years ago, it has the distinctive marker values DYS391=9 and DYS425=null. It also includes a group with DYS413=19,22 and many other distinctive marker values (name in this group include Riddick, Bigham, Zimmerman, Odgers etc). And it includes many other people who don't fit into any of these marker based clusters.

You can see all of these groups at the top of the FTDNA I-P37 project STR results page: https://www.familytreedna.com/public/I2aHapGroup/default.aspx?section=ycolorized

In December 2014 two people in I-PF6947 and three people in I-L672*  in M26*-France ordered the Big Y test, and now the tests are completed and we have this tree:

Because three people in the M26-France group did Big Y, we were able to find two branches. I recommend that all M26-France people test Y14720 and Y14722, or the Big Y. As more people in M26-France do Big Y or similar tests, we will quickly find new branches.

Only two people in I-PF6947 have done Big Y, so we only have one branch which shows the 18 SNPs that they share. As soon as a third person in I-PF6947 does Big Y we will be able to add another branch to the tree. And now PF6947, Y15579 etc. have been added to the official YFull tree:
At this point, it would be most useful for I-PF6947 people to do additional Big Y tests, perhaps the Crowley family could pool funds to order one Big Y, and the Healy/O'Donoghue family could do the same.

What tests should the other M26+ L672+ L160- people order? A Big Y would be useful for anyone, because we now have 5 Big Y results for comparison, Beyond that, I recommend a Y11222 test, I expect that all of these people will be Y11222+.

PF6947 is already available at FTDNA for $39. We have requested some of the new SNPs from FTDNA but have informed us that they will not add uncommon SNPs to their catalog at present. I suggest that you order the SNPs I have recommended (Y11222, Y14720, Y14722) from YSeq.net which is headed by Thomas Krahn, formerly of FTDNA. SNPs at YSeq cost $17.50 each. You will need to give a new cheek scrape sample, and there is a one time cost of approximately $5 for the sample kit and shipping.

I2a-M423 SNP panel test at Yseq.net, only $88

YSEQ has released a I2a-M423 SNP panel which covers 32 SNPs, the cost is only $88 (the same cost as two SNP tests at FTDNA, if this is your first test at YSeq you will need a cheek swab kit which is approximately $5):

http://www.yseq.net/product_info.php?products_id=11788&osCsid=f8285ed9dc40137e010ececd04d64ea3

I can recommend this test for all Dinaric-North and Dinaric-South people, and it also would be interesting for I-L161 Isles people who don't match any of the Isles groups very well. If you have already done Big Y there is no need to do this panel. Some more comments are below--Bernie

1) I2a-M423 includes the "Dinaric" "Disles" and "Isles" groups.

2) The YSeq M423 panel is very good for people who have not done STR marker
testing. For example, it's a very good test for people who have done the
23andMe test and who have received a paternal haplogroup of I2a2, I2a2a or
I2a2b. Or people who already know they are I2a-L621 (Dinaric and Disles) or
I2a-L161 (Isles) from some other test.
Of course, I recommend that people also do a 12, 25, or 37 STR marker test
at FTDNA.

3) The YSeq panel does not include some minor SNPs that have been included
in some trees (P41.2/M359.2, P61, V19, PF6316, CTS8849). In my opinion the
SNPs in the YSeq M423 panel are much more important than these minor SNPs.

4) The YSeq M423 panel is very good for all Dinaric people, all
Dinaric-North and all Dinaric-South. We can predict results for S17250 for
some Dinarics based on STR markers, but it is impossible to predict results
for any of the 14 more specific SNPs listed for CTS10228+ S17250- people
and CTS10228+ S17250+ people.

5) The YSeq M423 panel is very good for all Isles people. But in most
cases, if an Isles person has 37, 67, or 111 marker results we can predict
his results for these SNPs. Please feel free to email me or post here for
specific recommendations.

6) The Yseq M423 panel will not give much information to Disles people.

7) If you have done Big Y or similar tests, there is no need to do the YSeq
M423 panel. If you have already tested some of the SNPs on the panel,
please feel free to email me or post here for specific recommendations.

8) If you are a member of the FTDNA I-P37 (I2a) project, please send me a
copy of your YSeq results if you wish, because we have no connection to
YSeq and we will not be notified of your results.
