An article from the Chicago Tribune examines the impact of pop culture on baby names. According to the story, the names of some of the characters in Twilight have become more popular:
Bella, the name of the love-struck heroine of Stephenie Meyer’s vampire novels, hadn’t quite cracked the Social Security Administration’s list of the top 200 girls’ names in America when the first “Twilight” book was published in 2005. Today, it’s at No. 58, higher than Miley, Kingston or Maddox. Cullen, the last name of Bella’s vampire beau, Edward, is in the top 500 boys’ names for the first time in more than a century.
Other pop culture characters have supposedly influenced naming including Piper from Charmed and Samantha from Bewitched.
