Zara Tindall is an incredibly popular member of the Royal Family who is never afraid to show the close bond she shares with her relatives. As Princess Anne's daughter celebrates her 43rd birthday today (Wednesday, 15 May), there is one family relationship that is especially important - and it began during Zara's earliest days. Zara was born at St Mary's Hospital in Paddington on 15 May, 1981 and was Queen Elizabeth II's first granddaughter.
