Savannah Phillips is the oldest great-grandchild of Queen Elizabeth II and was born on December 29, 2010, to Peter and Autumn Phillips—who announced their separation in 2020.

Like her father Peter, who is Princess Anne's son, she does not have a royal title. Her father was not given a royal title and this was decided at birth for the sake of his future. 

Savannah will turn 11 at the end of this year.
