Here are the Y-haplogroups of US presidents known at present:
So far we have the presumed haplogroups 38 out of 46 presidents. None of the haplogroups are 100% certain as no president tested personally. The haplogroups were inferred based on triangulation of each president's genealogy and the results of descendants of a common shared ancestor. Those with a (?) next to the haplogroup are based on the haplogroups matching their surname in their ancestral region, but lacking clear data about the genealogy of the tested people.
- 2 are E1b1b => 5.5%
- 7 or 8 are I1 (Germanic/Nordic) => 14 or 16.5%
- 1 is I2a1a (British/Irish Neolithic)
- 2 are I2a2a-L801 (Germanic) => 5.5%
- 1 might be R1a
- 22 are R1b (61%) including:
Compared to the Y-DNA frequencies in Britain and Ireland, where most presidents' paternal lines originated, there are more E1b1b, I1, I2 and T1a than expected, but less R1b (Britain has 70% R1b and Ireland 81%). That's probably due to the small sample size though, which quickly adds more weight to minority haplogroups.
