Americans love Game of Thrones enough to start naming their daughters after one of its most popular characters.

According to The Baby Name Wizard Blog (via io9 ), there were 146 American girls born last year named Khaleesi after the title held by Emilia Clarke's character Daenerys Targaryen, Dothraki leader and the Mother of Dragons."That's a 450% jump in the name's usage from 2011, and before that year it was completely unknown," claims the blog.Not bad for a name that's a complete invention of author George R.R. Martin.
