Game of Thrones has inspired a surge in the number of babies being named Khaleesi in the US and Arya in the UK.
In 2012, 146 girls in the US were named Khaleesi. In fact in Games of Thrones it's not even a name, but a title meaning 'queen', which Daenerys Targaryen receives when she marries a clan leader.
In the UK 104 parents decided to call their newborn daughters Arya, presumably after the feisty Game of Thrones character.
Both names appear in author George R R Martin's series of best selling epic fantasy novels, which were translated to TV by HBO from 2011.
In the US less than five babies were called Khaleesi in 2010. The number rose to 28 in 2011, before peaking in the latest figures from 2012 at 146. While in the UK Arya jumped up 221 places in the chart of popular baby names from 2011 to 2012, according to the Office of National Statistics.
In 2012 in the UK there were 21 Khaleesis, 15 Theons, four Sansas and three Catelyns.
