LONDON (AP) - Britain's 3-month-old future monarch, Prince George, was being christened Wednesday, October 23, 2013 with water from the River Jordan at a rare four-generation gathering of the royal family in London. George, the son of Prince William and his wife, Kate, was being christened by Archbishop of Canterbury Justin Welby at the Chapel Royal at St. James's Palace. The infant wore a replica of an intricate lace and satin christening gown made for Queen Victoria's eldest daughter and first used in 1841. He arrived at the chapel in his father's arms with his mother by their side. He appeared to wave at his great-grandmother, Queen Elizabeth II, although it was really just William moving his infant son's hand up and down.
