Thanks to some Big Y-500 to Big Y-700 upgrades:

I-Y52831 is removed
I-A13912 is below I-FT14506 haplogroup



Thanks to a new sample, we split the I-Y151633 haplogroup

New tree specific to I-FGC56815 (part of I-L233 "Western")

Click here to download our first draft tree for I-FGC56815 (dated 2019-08-23)

The I-L233 haplogroup is sometimes nicknamed "Western" because it's found throughout Western Europe, but it's also found in Central and Eastern Europe (France, the Netherlands, Belgium, Denmark, Norway, Germany, Poland, Croatia, Albania, Moldova, Finland etc).

Probably I-L233 is most common in Great Britain, although much less than 1% of British men belong to I-L233. (And I-L233 is very rare in Ireland, it has only been found in families that arrived in Ireland within the last 1,000 years from Britain or from Continental Europe).

The common ancestor of I-L233 lived approximately 2000 years ago according to YFull's calculation. It had a very rapid expansion at the earliest stages, for example most I-L233 men belong to the major I-Y4252 branch which has at least 22 immediate child branches.

It's difficult to study the spread of I-L233 because British-ancestry men have done so much more DNA testing than men from other countries. Most of the named branches have only been found in Britain and most of the named branches contain only a few families.

But the I-FGC56815 branch is British and contains many families, and we have created a new tree specifically for I-FGC56815. Most of the families have ancestry from the southern half of England, or they are American and have unknown ancestry, probably from Great Britain.

Many updates: 2019-08-20 tree for I-Y4460

Click here to download our 2019-08-20 tree for I-Y4460

This tree shows many updates (indicated in red):

• some of the new samples on the tree are people who did Big Y-500 in 2018 or earlier, but joined our I-P37 project recently
• some of the new samples on the tree are people who didn't order Big Y-500, instead they ordered Big Y-700 in 2019
• there are some new branches on the tree thanks to people who upgraded Big Y-500 to Big Y-700

A possible new branch based on Big Y-700 results: 2019-07-08 tree for I-S17250

Click here to download our 2019-07-08 tree for I-S17250

This tree shows a new branch called I-FT39645, it's part of I-A2423. There are two A2423+ men who did Big Y-700, they share three SNPs called FT39645, FT42350, and FT43555. The prefix FT indicates that these SNPs were discovered in Big Y-700 results beginning in 2019 and were named by FTDNA.

But these SNPs occur in regions that weren't sequenced by the Big Y-500 test. It's possible that some of these SNPs are equivalent to A2423, and maybe all A2423+ men share some of these SNPs. Another A2423+ man has an Big Y-500 to Big Y-700 upgrade in progress, this will help us learn the correct placement of these SNPs.

This tree also shows some SNPs that are probably equivalent to Z16971, and three additional Big Y results.

2019-06-26 tree for I-S2703 (part of I-L161 "Isles")

Click here to download our 2019-06026 tree for I-S2703

We have created a new tree for the more specific I-A2330 branch (click here).
And the more specific I-Y14612 and I-S3723 branches already have their own trees.

This I-S2703 tree shows details about Big Ys and SNPs for all branches of I-S2703, except I-A2330, I-Y14612 and I-S3723

Our first tree for I-A2330 (part of I-S2742 "Isles")

Click here to download our 2019-06-26 tree for I-A2330

I-S2703 is a large part of the I-L161 haplogroup.

According to current knowledge, everyone in I-S2703 belongs to one of two branches:
I-Y3723 which is found in Ireland and Great Britain, and which includes all of the Isles-C and Isles-D clusters.
I-S2742, which is a complex group found in Britain and Ireland, but also in Germany, Poland, Scandinavia etc.

For reasons of legibility we have created a new tree for I-A2330, it's part of I-S2742.

FT16449 seems to be an important SNP immediately below PH908: 2019-06-04 tree for I-PH908

Click here to download our 2019-06-04 tree for I-PH908

This tree shows more information about a SNP named FT16449. It's immediately below I-PH908. We included FT16449 on our previous draft tree, but with this update we show that some additional branches can be placed in I-FT16449.

Unfortunately FT16449 is inside a so-called X-transposed region which is very similar (99,5%) to a region on the X chromosome. This means that FT16449 is not suitable for individual SNP testing.

But FTDNA has already added the I-FT16449 branch to their haplotree and to their Big Y Block Tree. FTDNA has also added the I-FT14506 branch to their trees.

I-FT16449 and I-FT14506 are both part of the DYS561=16 cluster. There are several additional branches in this cluster, but no one from these branches have tested FT16449 and FT14506 because these SNPs occur in regions that weren't covered by the Big Y-500 test. See the tree for more details.
