From the website from whence this meme cometh:
"...not every name is on the list.
A certain number of instances of a name were required to even make the list.
About 10% of all responses were not included on the list
because they appeared too few times.
So, uncommon names are not represented on the list."
I've seen only a few Brian Epsteins online, and
some of them even admit that their parents did
name them in honor of THE Brian Epstein
Thanks for the germ of an idea, trefenwyd!
