New Big Y-700 samples in I-L1294 "France" and I-A8689 "Alpine", and ancient DNA samples: 2021-03-27 tree for I-S21825

 Click here to download our 2021-03-27 draft tree for I-S21825 

I-S21825 contains some of the least common branches in I-P37. All known modern men in I-S21825 belong to one of four branches:

• I-L1294 "France", this is the group with DYS388=9. Almost all known samples at FTDNA have British/Irish origin, but this group may be more common in France and Spain. 
• I-M838 also known as I-L880 "Northern France" this is a poorly known group with a MRCA who lived 6400 years ago according to YFull's estimate. There are only two Big Y/NGS samples of modern men for this group, both are Big Y-500 samples
• I-L233 "Western" which has a MRCA who lived 2100 years ago. There are 193 Big Y samples for I-L233
• I-A8689 "Alpine" also known as I-Y11949, which has a MRCA who lived 2900 years ago. This group is closely related to I-L233

This I-S21825 tree shows details about all of these branches except I-L233, which has several trees of its own.

This update shows a new branch in I-L1294 thanks to a new Big Y-700 sample. There are now 2 Big Y-700 samples and 5 Big Y-500 samples for I-L1294.

There are now 3 Big Y-700 samples and 1 Big Y-500 sample in I-A8689 "Alpine". One of the Big Y-700 tests was completed in December 2020, he has origin from Turkey according to FTDNA's trees. But he isn't a member of the I-P37 project and we have no way to communicate with him. His result didn't add a new branch to the tree, he belongs to an unnamed I-A8689* branch.

As mentioned, I-M838 contains only two modern samples, one with origin in northwestern France and one with origin in Rheinland-Pfalz in Western Germany. But FTDNA and YFull show an ancient DNA I-M838 sample. This is ERS3968402, from a Wartburg culture collective burial also in Rheinland-Pfalz (approximately 5200 years old). See https://www.biorxiv.org/content/10.1101/851188v1  The common ancestor of ERS3968402 and the German Big Y-500 sample lived approximately 5700 years ago, they form the new I-BY73844 branch. We will try to organize Big Y-700 tests for more members of I-M838.

This update also shows major new branches named I-FT344596 and I-FT344600. These are based on ancient DNA samples from Ireland and Sweden as shown on the YFull and FTDNA trees. See https://www.yfull.com/samples-from-paper/443/ and https://www.yfull.com/samples-from-paper/388/ 

There are several additional ancient DNA samples/branches that are shown on FTDNA and YFull's tree, see links below

Many new branches: 2021-03-27 draft tree for I-Y4882

Our last draft tree update was in March 2021, and this new tree shows many new branches, but some were discovered several months ago. Here are all the new branches on this updated tree:

• I-Y46518 is included in FTDNA's trees but it's based on only one Big Y Participant. We aren't aware of any other I-Y46518 samples. FTDNA added this branch in January 2021
• I-FT156638 was discovered in January 2021
• I-FGC30465 was discovered in July 2020
• I-FT59351 was discovered in November 2020
• I-Y40408 contains three samples: one Big Y-700 sample (Poland), one Big Y-500 sample (Serbia), and one Dante Lab sample (Poland). This branch doesn't currently appear on the FTDNA tree, I expect FTDNA will add I-Y40408 soon. 
• I-FT114748 is below I-Y40408. The Big Y-700 sample (Poland) and the Big Y-500 sample (Serbia) share FT114748 and two other SNPs, the Dante Lab sample (Poland) apparently has negative results for these SNPs. All three men have ordered the YFull analysis, and YFull might add I-FT114748 at a future update.
• I-FT109194 (samples from Bulgaria and Montenegro, both Big Y-700) was discovered in January 2021, it's part of I-FT109380 which also includes a Big Y-700 sample and a Dante Lab sample (both from BiH)
• I-FT26700 was discovered in July 2020, it has two Big Y-700 samples, they aren't I-P37 Project members, one has origin from Slovakia and the other doesn't list his origin

I-Z16973 is an important new level below I-Y3106: 2021-03-25 tree for I-Y4460

Update 2021-03-28: We communicated with YFull, and YFull will add this level to their tree. Click here to see the live version of the YFull I-Y3106 tree.

Our updated I-Y4460 draft tree shows a new level called I-Z16973, it's immediately below I-Y3106.

Four branches of  I-Y3106 have Z16973+ results:

• I-Y3118
• I-FT10545
• I-FT78951
• I-Y47356 

Three branches of I-Y3106 have Z16973- results:

• I-A6106
• I-S8201
• I-BY53671

Z16973 occurs in the DYZ19 repeat region, and maybe FTDNA won't add it to its tree. But Z16973 gives consistent results.

This update also shows a new branch called I-BY111745, it's part of I-BY53671

New branches in Isles-D3/D99 and in the Todd cluster: 2021-03-17 draft tree for I-Y3723

Click here to download our 2021-03-17 draft tree for I-Y3723

This update shows a new branch in I-S7708, also known as Isles-D3/D99, and a new Big Y sample in an existing branch.

This update also shows a new branch called I-FT99343, it's in I-A10514. We don't have a good nickname for  I-A10514, we sometimes call it the "Todd cluster" after the first I-A10514 family who did Big Ys.

No longer strictly British: 2021-03-16 draft tree for I-A8462

 Click here to download our 2021-03-16 draft tree for I-A8462

This update shows a branch named I-FT286898, it's immediately below I-A16520. Now FT286898 is the only SNP at its level, and FT286185 and several other SNPs are at a more specific level. Previously all of these samples were considered to be equivalent.

There is now one I-A8462 sample from Continental Europe: a German man with German ancestry, he belongs to an I-A8462* branch, so he's not closely related to any other known I-A8462 man. Unfortunately he's not a member of the I-P37 project, but you can see his German flag on FTDNA's public haplotree (see link below).

Four new branches and three new I-A815* samples: 2021-03-01 tree for I-S17250

Click here to download our 2021-03-01 draft tree for I-S17250

This tree shows four new branches:

• I-FT67655 (Germany, Czech Republic and another sample has maybe Polish origin)
• I-FT9248 (Germany and unknown origin)
• I-Y65151 (northern Serbia and southwestern Romania). This branch is new, we expect FTDNA will add this branch soon
• I-FT399454  (Germany and Slovakia), part of I-A2423
  
  

The new I-FT9248 and I-Y65151 branches are part of I-A815. This update also shows three new I-A815* Big Y samples. I-A815 now has 14 immediate child branches: four named branches which contain multiple samples and ten unnamed I-A815* branches which each contain only one sample. (one of the I-A815* samples isn't a member of the I-P37 project).
