Miss Rhys-Jones met Prince Edward at a real tennis event in the summer of 1993.
The couple announced their engagement in January 1999, and the wedding ceremony took place at St. George's Chapel, Windsor Castle, on 19 June 1999.
On the day of the wedding, it was announced that The Queen had conferred the titles of The Earl of Wessex and Viscount Severn upon Prince Edward. Upon her marriage, Miss Rhys-Jones became known as Her Royal Highness The Countess of Wessex.
In keeping with the tradition of using Welsh gold for Royal wedding rings, the gold for the wedding rings of The Earl and Countess came from The Prince Edward mine in Trawnsfynydd, Gwynedd, North Wales.
Their Royal Highnesses have two children, Lady Louise, who was born on 8 November 2003 and James, Viscount Severn who was born on 17 December 2007.

On the occasion of their marriage, Their Royal Highnesses founded The Wessex Youth Trust, a grant making organization to help, support and advance registered charities which provide opportunities specifically for children and young people.
These charities represent a huge cross-section of different youth-orientated causes and needs: from hospices, hospital beds and incubators to holiday clubs, sports organisations and outreach programmes; from inner city drop-in centres, child protection training and helplines to drug prevention schemes and sex education; from deaf, blind and speech impaired support groups and special needs libraries, to theatre, dance and music-related groups. Since 1999 donations have been made to over to over 154 charities, both in the UK and internationally.
