I was just looking up r1b. I came across it while researching Ireland.
The following are historic people or dynasties that may belong to the R1b haplogroup, as suggested by the testing descendants or other relatives:
Males of the House of Bourbon and, by extension, all branches of the Capetian dynasty. (R1b1b2a1a1b / R-Z381).
Charles Darwin.
Niall of the Nine Hostages.
The Egyptian pharaos Amenhotep III, Akhnaton and Tutankhamun
President John Adams and his son John Quincy Adams carried haplogroup R1b-S1200, confirmed by the Adams DNA project.
President Woodrow Wilson carried haplogroup R1b-P312, confirmed by the Wilson DNA project.
Thomas Edison likely carried haplogroup R1b, according to the Edison Y-DNA project.
Benjamin Franklin carried haplogroup R1b, according to the Franklin DNA project.
John Witherspoon belonged to R1b-U106, based on the results from the Witherspoon DNA project.
A lot of those from Ireland ended up in Utah (via mormons)
