Version History     Last revision date for this specific page: 21 July 2014

Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG does its best to keep the tree updated with the latest developments in the field. The viewer may observe other versions of the tree on the Web. Email Alice Fairhurst if the differences need clarification or if you find any broken links on this page.

Private SNPs are being removed from the tree and placed in the following category:
Private SNPs - After investigation these SNPs have not met the population distribution criteria for placement on the tree: either too few confirmed positive testers have been found OR multiple confirmed testers were confined to a single surname or to a small group of related males.

SNPs under Investigation - Additional testing is needed to confirm adequate positive samples and/or correct placement on the tree.

NOTES:

Y-DNA haplogroup T is found at low frequencies throughout Europe and in parts of the Middle East, North Africa, and East Africa. A famous person in Haplogroup T was Thomas Jefferson (1743-1826), the third President of the United States from 1801 to 1809.
