Prince William and his wife, Kate Middleton, named their first-born child George Alexander Louis, Kensington Palace said Wednesday.
In a brief communique, it was announced that the infant will be known as His Royal Highness Prince George of Cambridge.
George was the favored name in Britain in the pre-announcement oddsmaking, and it was also the official name of Queen Elizabeth's father, George VI.
The name of the baby, who is third in line for the British throne, was virtually the only thing that remained unknown in the wake of his birth last Monday.
The duke and duchess of Cambridge and the little prince left St. Mary's Hospital on Tuesday and, after spending the night at Kensington Palace, on Wednesday they went to the home of Kate's parents in the town of Bucklebury.
Earlier, they had received a visit from Queen Elizabeth II, who stopped by the couple's official residence in London to have a look at her third great-grandchild.
The visit of the 87-year-old sovereign came a few days before she travels to Balmoral, Scotland, to begin her summer vacation.
On Tuesday, while he was still in the hospital, the new prince received a visit from his maternal grandparents, Michael and Carole Middleton, and his paternal grandfather, Prince Charles, who was accompanied by his wife, Camilla, the duchess of Cornwall.
Cannonades and the pealing of bells celebrated the birth of Prince George of Cambridge earlier in the week. EFE
