Prince Edward, the Queen's youngest child, married Sophie Rhys-Jones in St George's Chapel, Windsor. A procession of open-topped, horse-drawn carriages carried the pair to the reception in the St George's Hall in Windsor Castle, past crowds of several thousand people. Sophie's dress, by designer Samantha Shaw, consisted of a long, fitted coat with long sleeves and an ivory train, made from hand-dyed silk organza and hand-dyed silk crepe, with rows of pearls and crystal beading. In total, 325,000 cut-glass and pearl beads went into its design. Buckingham Palace announced before the wedding that the couple would in future be known as the Earl and Countess of Wessex. It was also agreed that Edward will become Duke of Edinburgh after the death of his mother and father. The couple have two children: Lady Louise Windsor, born in 2003, and James, Viscount Severn, born in 2007.
