Our August 19 tree is most current of course.

The August 17 tree shows a new Big Y highlighted in red at the very top of the tree. This is the second Big Y for the "Isles-B4" cluster. Isles-B4 is a small cluster with distinctive STR marker values, especially DYS388=11, and Isles-B4 is found only in Great Britain and Ireland (mostly England). FTDNA now calls this branch I-PH3480. There is also an anonymous Irish sample from the P. Hallast study in this branch (ire-94).

The August 19 tree provides more details about the SNPs in the I-PH3480 branch, now that we have looked at the VCF file from the new Big Y.

The August 19 tree also shows a new Big Y for a German-American man. He shares two SNPs (A20828 and BY50244) with two English-ancestry men. But he has 28 private variants (SNPs) not found in the English men, and probably his common ancestor with them lived 3500 or more years ago.
