She is only a few hours old, yet already the baby daughter of Zara Phillips and Mike Tindall has caused the Royal Family's line of succession to change. The new baby will be a future playmate for her second cousin, six- month-old Prince George of Cambridge - to whom Zara is a godmother. The baby also has two first cousins on the royal side of the family - Peter and Autumn Phillips' daughters Savannah and Isla. Sixteenth in line to the throne, her arrival means that the Queen's nephew Viscount Linley shifts down one place in the line of succession to 17th. While the newborn is the Queen's fourth great-grandchild, but will not bear a royal title.
