Queen Elizabeth Welcomes First Great-Granddaughter, Autumn Phillips' Daughter

Queen Elizabeth II will ring in 2011 with an extra-special addition to the royal family: her first great-granddaughter.

As the BBC is reporting, the Canadian-born Autumn Phillips, wife of the Queen's grandson Peter Phillips, gave birth to a baby daughter on Wednesday. The newborn, whose name has not yet been released, is 12th in line to the throne.

According to the Associated Press, Buckingham Palace officials issued a statement confirming the birth at Gloucestershire Royal Hospital on Wednesday. The baby weighed 8 pounds and eight ounces (3.8 kilograms).

"The Queen, The Duke of Edinburgh, The Princess Royal, Captain Mark Phillips and Autumn's family have been informed and are delighted with the news. The baby's name will be confirmed in due course," the statement read.

Peter Phillips is the only son of Princess Anne and her first husband, Captain Mark Phillips. He does not have a royal title because his mother turned down the Queen's offer of honors for both her children. His younger sister Zara Phillips announced her engagement to the rugby player Mike Tindall earlier this month.
