Harry and Meghan named their daughter Lilibet Diana as a meaningful homage to two family members: the Duke of Sussex's grandmother, the late Queen Elizabeth — whose childhood nickname “Lilibet” was used by her closest family — and his mother, the late Princess Diana, who died in a car accident in Paris in 1997 when Harry was just 12.

The Duchess of Sussex, Meghan Markle, took to Instagram with a series of previously unseen family photos to mark Princess Lilibet's fourth birthday, sharing how she brightens their days.
