21 British babies named after Game of Thrones character Khaleesi

Harry, Oliver and Jack held on to their top spots as most popular boy's names in 2012, while Amelia, Olivia and Jessica were most popular for girls, according to the Office for National Statistics.

Taking the different forms of spelling into consideration, Muhammed (also, Mohammed and Mohammad) was the second most popular boy's name last year.

In 2002, by comparison, the top boy's names were Jack, Joshua and Thomas (in a respective third, eleventh and sixth in 2012), while the top girl's names were Chloe, Emily and Jessica (sixteenth, fourth and third last year).

Digging a little deeper though, and some amusing facts appear among the statistics.

For example, taking joint 259th place for boys last year were Aston and Martin.

And popular fantasy drama TV series Game of Thrones seems to have had quite an impact on some parents.

Some 21 girls were named Khaleesi, a title from the series referring to the wife of the leader of the Dothraki. In the US, there are currently 146 girls with this name.

Other girls include three Catelyns (the wife of Lord Eddard Stark and Lady of Winterfell), four named Sansa (the elder daughter of Eddard and Catelyn Stark) and 104 called Arya (the third Stark child).

Meanwhile, four boys were called Tyrion, presumably after Tyrion Lannister, a dwarf from an esteemed family in the series. Some 15 were named Theon, the son and heir apparent of Lord, later King, Balon Greyjoy and eight named Bran (another Stark child).

Here's the results from the ONS.
