I just went down a baby name rabbit hole after reading the Gawker post about how North West really wasn't that terrible of a name. I didn't realize that Madison became a popular name specifically because of Splash but it makes total sense since it didn't really exist as a first name before 1985.
Then I found a blog post proclaiming that there were 146 baby girls named Khaleesi in the United States. One hundred and forty-six children named Khaleesi. For me, Arya or Sansa or even Cersei is one thing. They're names, not honorifics. But Khaleesi. I don't know about that.
