Princess Charlotte Elizabeth Diana, Two

Princess Charlotte of Cambridge is the second child of Prince William and Kate Middleton.

The name's royal pedigree includes Queen Charlotte, wife of George III, who bore him 15 children and helped found Kew Gardens. Queen Charlotte's and Chelsea Hospital, which is named after her, is part of the same NHS Trust as St Mary's Hospital Paddington, where the Duchess of Cambridge gave birth to her three children. Prince William and Prince Harry also were born in the hospital.

Queen Charlotte’s granddaughter, Princess Charlotte of Wales, married May 2, the day the new Princess Charlotte was born. The younger Charlotte died in childbirth in 1817 at the age of 21. She was the only child of George, Prince of Wales, who would go on to become King George IV.

Charlotte also happens to be the middle name of the duchess' sister, Pippa Middleton, and goes back in her family to her paternal great-great-great-grandmother, Charlotte Ablett, born in 1825.
