The wife of the Queen's youngest son, Prince Edward, went on to have two successful pregnancies, and her children Lady Louise and Viscount James Severn are now 16 and 12, respectively. On Thursday, she visited the Thames Valley Air Ambulance base at White Waltham as they marked their 21st anniversary – and just ahead of a week of celebrations for the service across the U.K. Sophie, Countess of Wessex.
