The queen's first great-grandchild, Savannah Anne Kathleen, was born in December 2010 and is the daughter of Peter Phillips (the queen's first grandchild and son of Princess Anne) and his wife, Autumn. You might know the spunky 7-year-old from such hits as "Shushing Cousin George," "Pushing Cousin George," and "Making Cousin George Laugh."
Savannah is currently 15th in line for the throne, and will move down a spot once Meghan and Harry welcome their first child. Her grandmother, Princess Anne, declined the queen's offer to give royal titles to both Peter and his sister Zara when they were born, so Savannah doesn't have one either. She may not carry an HRH, but something tells us this royal prankster will continue to make headlines regardless.
