The second royal baby was born on May 2 and is fourth in line to the British throne, following big brother Prince George, who is 1 and 1/2, their dad and their grandfather Prince Charles, Diana's ex-husband. Her name was revealed on Monday. She is the most prominent member of the extended royal family to be named after the late Princess of Wales...but is not the first overall.
"Perfect names," Charles Spencer, the ninth Earl Spencer, said on Twitter on Monday. "My 2-year old Charlotte Diana will be thrilled at cousinly name-sharing. Is at an age where thinks world revolves around her!"
Lady Charlotte Diana Spencer is his seventh child and first with third wife Countess Karen Spencer, formerly Karen Gordon.
Charles Spencer is the younger brother of Diana, one of the U.K.'s most beloved royals, who died at age 36 in a car crash in 1997.
All of Princess Charlotte's names bear a special meaning to both sides of her family. It is a female version of Charles, which pays tribute to William's father, and is also the middle name of Kate's sister Pippa Middleton and her mother, Carole Middleton. Elizabeth is the name of William's grandmother and the reigning queen, Queen Elizabeth II and is also Kate's middle name.
