The Social Security Administration released its annual rundown of the most popular names for newborns on Friday, and flying up the list was an ancient name with modern fame: Cullen, the surname of one handsome bloodsucker, Edward, in the frighteningly popular vampire series “Twilight,” based on the best-selling novels by Stephenie Meyer.

Cullen materialized at 485, leaping almost 300 spots from 2008 for the biggest increase of any boy’s name; it wedged firmly between Braiden and Kason.

But the nation’s fascination with the undead may not end there. The most popular boy’s name was Jacob, an eternal favorite that happens to be the name of the buff rival of paler-than-thou Edward: Jacob Black. The most popular name for girls was Isabella, the progenitor of Bella, the love interest of both Edward the vampire and Jacob the werewolf. Just plain Bella logs in at 58.
