- Queen Elizabeth's great-grandchildren have an adorable nickname for her: "Gan-Gan."
- Although the nickname has become famous among royal fans as the Cambridge kids' name for the Queen, it was actually coined two generations earlier in the royal family.
- A brochure from Prince Charles' 1969 investiture as the Prince of Wales revealed that Charles came up with the nickname for his own grandmother, Queen Mary.
Queen Elizabeth might be "Your Majesty" to most people, but to her great-grandkids, she goes by a much simpler (and more adorable) moniker: Gan-Gan.
Kate Middleton shared that adorable tidbit with the world during her first solo interview in 2016, according to The Sun. At the time, Prince George was the only royal kid using the nickname, but his sister, Princess Charlotte, reportedly uses it now, too.
"George is only two-and-a-half and he calls her 'Gan-Gan,'" Kate explained. "She always leaves a little gift or something in their room when we go and stay and that just shows her love for her family."
The nickname's origins go even further back in the royal family's history though. According to Express, the nickname traces its roots back to George's grandpa, Prince Charles, who came up with the name when he was a kid.
The paper cited a souvenir brochure from Charles' 1969 investiture as the Prince of Wales when sharing the story of "Gan-Gan's" origins.
"His mother spent as much time with her son as her duties allowed and part of the day was always devoted to him," the brochure read. "Often, he was taken to visit Queen Mary—whom he called Gan-Gan—at Marlborough House and the Queen—later known as the Queen Mother—as Buckingham Palace."
