This tree shows two new samples in different branches of I-A7729. One man has ancestry from County Longford, Ireland and the other man is American with likely Irish ancestry from an unknown county.

Three new samples: 2019-11-23 tree for I-FGC56815

Click here to download our 2019-11-23 tree for I-FGC56815

This tree shows the following updates:

  • a new I-FGC56815* sample, he is American with 1700s ancestry from Scotland near Glasgow
  • a new Big Y for a member of the American Terry family
  • a third sample in the I-A21933 branch (which FTDNA calls I-BY50117). Two of the men are from the American Scott family. The third man is English with a different surname. But all three men are close STR matches to some American men who have a surname very similar to the English man.
All known members of I-FGC56815 have English or Scottish paternal ancestry.

A third sample in a Scottish branch of I-PF4189: 2019-11-22 tree for I-CTS11338

This update shows a third Big Y sample in I-BY67299. This is a large cluster below I-PF4189 that contains a large family named Barclay and other Scottish and northern English families. The I-BY67299 branch isn't yet on FTDNA and YFull's trees.

Two of these men have ordered the YFull analysis, YFull currently shows these samples in the I-Y89254* section. In a few weeks, YFull will add the new branch and calculate a MRCA age.

FTDNA currently places these samples in the I-Z44354* section of the Big Y Block tree. Y89254 and Z44354 are equivalent SNPs.

When YFull and FTDNA add the new branch, maybe they will name it I-BY67299 or maybe they will chose another SNP to name the branch.

A new I-A10029 sample with 68 private variants: 2019-11-22 tree for I-L161

Click here to download our 2019-11-22 tree for I-L161

We are still finding I-P37 samples which are very distantly related to any previous sample. This tree shows a new sample who has 68 private variants that haven't been reported in any previous I-P37 Big Y result.

He belongs to I-A10029 which is a rare branch below I-L1498. Most I-L1498 men belong to the large I-S2703 branch which contains all of Isles-C and Isles-D and a large part of Isles-B. But I-A10029 isn't part of I-S2703. The other I-A10029 men are from Scotland and Germany, and there is one American man whose European ancestry is unknown, it could be Germany or Ireland according to his family stories.

There are now very few members in the general I-L161 and I-L1498 sections of our I-P37's project STR results page. In almost every case, we can predict a more specific haplogroup based on STR marker patterns.

A new sample in I-A19385: 2019-11-21 tree for I-L233 tree

Click here to download our 2019-11-21 tree for I-L233

This update shows a new sample in I-A19385, he is American with British ancestry.  I-A19385 also contains men with French-Canadian and Finnish ancestry. Many branches of I-L233 "Western" have only been found in Great Britain and Ireland at this point, I-A19385 seems to have a wider distribution.)

18 branches in the I-L233 Lindsay family: 2019-11-20 tree for I-FT11343

Click here to download our 2019-11-20 draft tree for I-FT11343

This tree shows a new branch called I-FT67534.

Almost all samples on this tree are named Lindsay, Lindsey or Lindesay. A few samples have other surnames, but they belong to downstream branches and very likely had a Lindsay paternal ancestor at some point in the past.
