When the Duke and Duchess of Sussex announced the birth of their second child - a daughter - the couple also revealed her name: Lilibet 'Lili' Diana Mountbatten-Windsor. As with many names in the British royal family, the name honors ancestors and relates not to one but to two women of special importance to Prince Harry.

Lilibet: The name Lilibet may seem a bit unusual at first glance. The name is a dedication to the queen, as with this name she was affectionately called within the family.

The nickname dates back to childhood, when the queen was unable to pronounce her name properly. The queen's husband, Prince Philip, who passed away in April, also used the name for the queen.

Diana: The baby's second name is Diana, chosen to honor the memory of the late grandmother, Lady Diana.

Mountbatten-Windsor: The surname Mountbatten-Windsor is the personal surname chosen by many family members. It is a combination of the Queen's surname - Windsor - and Prince Philip's family name.

The Times of London reports that Harry spoke in advance with his grandmother to get approval regarding the name.

The daughter of the couple Harry-Meghan, the eighth in line for the throne, will be known as Lily, an attempt to slightly modernize the name. In addition, the name refers to the lily flower that symbolizes purity.
