I was noticing the same thing.
That's because the names most people pick -- especially if you count screwed up "creative" spellings -- never get enough numbers to win any numbers contests.
However, I bet the % of people who have one of these "top 10" names is quite low. Because most worldly people I know use the "Last name" style first names. I mean, pick ANY last name, and people gladly choose that for the first name for their boy or girl.
Carter, Compton, Reagan, McKenzie, Peyton, Colton, Addison, you name it.
I remember in the 80's Addison-Wesley had a popular line of school math textbooks. But those were the LAST NAMES of the individuals involved.
