My father had this Y-chromosome, as did his, father, and his father before him, and so on. Every man's Y-chromsome is passed on in the same way as we pass on surnames. All those with R1b-U106 will share the same male ancestor (father's father's father's father's....etc.). Nobody really knows how long ago or where that man lived.
Famous people known to be R1b-U106 (from here):
- U.S. Civil War General (and later President) Ulysses S. Grant,
- U.S. President Polk,
- The royal Bourbon line of France, including the king they beheaded after the 1789 French Revolution (multiple descendants tested to determine this).
Note on Names: The R1b-U106 Y chromosome variant is sometimes called R1b-S21, other times called R1b-M405, and formerly called the totally-unmemorizable "R1b1b2a1a1". That's what we get for the field of genetic testing being so new. From what I can tell, by 2014, R1b-U106 is now the dominant name.
