Thousands of parents took heed of the Dothraki language while naming their newborns following the show’s premiere in 2011, so Lucy’s child isn’t the only one walking round with the same name as the silver-haired fan-favourite.
“I call her Cally for short, but she always introduces herself as Khaleesi Holloway, Queen of Dragons,” Lucy said.
But so far, the mum seems to be the only parent struggling to get her kid a passport because of it.
Speaking to the BBC, she said: “I was absolutely devastated, we were so looking forward to our first holiday together.
“It was the first I’ve heard of such a thing – I was astonished.”
Officials said they were unable to issue a passport unless Warner Brothers gave them permission, as the film studio owns the name’s trademark, prompting Lucy to seek legal advice after receiving the barmy response.
Lucy continued: “That information was sent to the Passport Office who said I would need a letter from Warner Brothers to confirm my daughter is able to use that name. I didn’t understand and felt frustrated.
