LONDON (AFP) - Queen Elizabeth II has become a great-grandmother for the second time, Buckingham Palace announced late Friday. Isla Elizabeth Phillips was born Thursday at the Gloucestershire Royal Hospital in Gloucester, southwest England, weighing seven pounds and four ounces (3.29 kilograms). She is the second child of Peter Phillips, 34, and his 33-year-old Canadian-born wife Autumn, following the birth of Savannah Phillips in December 2010. Phillips is Queen Elizabeth’s oldest grandchild and the son of her only daughter, Princess Anne, the Princess Royal. Anne, 61, decided that her children would not bear royal titles and her son keeps a low profile, carrying out no royal duties.
