Other Game of Thrones names that have risen in popularity include Arya and Brienne for girls, and Tyrion and Theon for boys.
They are part of a renewed fondness for names dating from medieval times, including Darcie, Elvina, Audrey and Winnie for girls, and Alfred, Wyatt, Jackson and Ellis - a version of Elijah - for boys.
Another Middle English name, Harper, has soared in popularity after being chosen by Victoria and David Beckham for their daughter.
Oliver and Amelia still top the charts, followed by Jack and Olivia. The only change from the top ten of 2013 was that Lily replaced Mia.
New entrants in the girls' top 100 included Robyn, Nancy and Lottie.
Siobhan Freegard, founder of Netmums and Channel Mum, a video blogging site for parents, said: "While Victorian and Edwardian names have been popular for some time now, this year's list shows parents are now searching much further back in time, even to the Middle Ages.
"Parents are looking for something they have not heard very often but which is not too 'celebrity culture'.
"Medieval names offer something different but which will not fall too quickly out of fashion."
