Another branch immediately below I-Y4252: 2020-01-09 tree for I-L233

Click here to download our 2020-01-09 tree for I-L233

This update shows 4 new branches:

  • I-Y85503 is a new branch immediately below I-Y4252. There are now 11 immediate child branches of I-Y4252, nine contain multiple samples and have been named, and there are only 2 unnamed I-Y4252* branches. 
  • As a reminder, many branches have been grouped together in the I-FGC56883 branch. FGC56883 isn't suitable for individual SNP testing, and the I-FGC56883 branch doesn't appear on the YFull tree or FTDNA's tree. But we have observed very consistent results for FGC5688 and we include it in this draft haplotree
  • This tree also shows a new branch called I-FT85526, it's part of I-Y85503. The two samples in I-FT85526 have different surnames but they are closely related to each other
  • I-FT85135 is a new branch below I-BY117344. The two samples in I-FT85135 are closely related and they have the same surname
  • I-Y85139 is a new branch below I-A7111

I-Y85503, I-BY117344, I-Y85139 and their subbranches contain only British-origin samples according to present knowledge.

more results in I-Z113: 2020-01-05 tree for I-CTS11338

Click here to download our 2020-01-05 draft tree for I-CTS11338

This tree shows a new branch in I-SK678 (part of I-Z113). The sample was given by a man who was born in England and whose paternal ancestors have presumably lived in England for hundreds of years. I-Z113 has an MRCA who lived 1550 years ago according to YFull's calculation. Most known members of I-Z113 are from Spain, Portugal and France but there are some other English members, and none known from other countries.

This tree also shows a new SNP called FT94805, it's equivalent to Y140451.  The placement of  FT94805 was confirmed thanks to a Big Y-500 to Big Y-700 upgrade. (These SNPs are in a different branch of I-Z113)

Three new branches: 2020-01-03 tree for I-Y4460

Click here to download our 2020-01-03 draft tree for I-Y4460

This tree shows the following updates:

  • I-FT104884 is a new branch below I-FT78951. I believe both samples have paternal ancestry from Ukraine.
  • I-FT152146 is a new branch below I-Y3118. One sample has paternal ancestry from Finland and the other has paternal ancestry from Turkey.
  • I-PH5047 is a new branch below I-S8201. One sample did a Big Y-700, he has paternal origin from Tatarstan. The other sample has Greek paternal origin, and was part of  P. Hallast's 2014 survey (sample ID was gre-86).
  • FT7391 is a new SNPs, it's equivalent to FT8963. This I-FT8963 branch is below I-FT10545

new Lindesay branch: 2020-01-03 tree for I-FT11343

Click here to download our 2020-01-03 draft tree for I-FT11343

This tree shows a new branch called I-FT123395. The two members are named Lindesay. Most members of I-FT11343 use the spellings Lindsay and Lindsey. I-FT11343 also contains a few men with other surnames, but probably they had Lindsay paternal ancestors in previous generations.

Major northern Irish branch in Disles-B: 2020-01-01 tree for I-L621

Click here to download our 2020-01-01 draft tree for I-L621

Many branches of "Disles" are found in Great Britain and Ireland. One of the most common branches is I-BY89974, which is shown on this updated tree. The members of I-BY89974 are mostly from the northern part of Ireland and from Scotland, and they have the distinctive marker value DYF395S1=15-17.

2019-12-22 draft tree for I-CTS10228

Click here to download our 2019-12-22 draft tree for I-CTS10228

This tree shows the following updates:

  • A new branch called I-Y81696, it contains two Big Y samples, they are the only known CTS10228+ and S20602- men. This update also resolves the position of several SNPs that are equivalent to CTS10228 and S20602, compare to our 2019-10-14 I-CTS10228 tree. The two I-Y81696 men both have paternal ancestry from southwestern Germany/neighboring areas of France, and they share the distinctive marker value DYS565=9 with the I-S20602 men.
  • we have created a new draft tree specifically for the major I-Z17855 branch, click here
  • a new branch called I-Y87441, it's part of the Jewish Dinaric cluster
  • as a reminder, there are only two known I-S20602* men. FTDNA lists a third man (kit 117308) as I-S20602*, but in fact he has Y18331+ results according to his Big Y-500 and his Big Y-700 upgrade. His Big Y-700 reported only 7 reads for Y18331, all 7 reads were positive A+ reads. He has Greek paternal ancestry, like almost all men in I-Y18331
