Lady Louise Windsor

In May 2019, Louise took part in the Private Driving Singles carriage drive at the Royal Windsor Horse Show and achieved third place.

In August 2018, Louise accompanied her mother, patron of UK Sail Training, to Haslar Marina in Portsmouth Harbour to meet a group of young girls working towards earning their qualification on an entry-level course of the Royal Yachting Association. In the same month, mother and daughter attended the final of the Hockey Women’s World Cup in London. The Countess has a great interest in the sport and is the patron of England Hockey. At age 14, Louise was a special attendant at the wedding of Princess Eugenie and Jack Brooksbank. To celebrate her 15th birthday in November 2018, mother and daughter made a cameo appearance on Strictly Come Dancing as they watched the popular BBC show from the audience. The Countess accompanied by her daughter, Louise, attended the International Horse Show at Olympia, London in December.

Lady Louise attended St George's School, Windsor Castle before moving to St Mary's School Ascot in 2017 for her year 9 school year.

Lady Louise was taught to ride at a young age and joined her father on horseback as part of the Queen's 90th birthday celebrations in Windsor in 2016. She has taken up carriage driving, a sport popularised in Britain by her grandfather, Prince Philip. In May 2017, she was responsible for leading the carriages of the Champagne Laurent-Perrier Meet of the British Driving Society at the Royal Windsor Horse Show.

In April 2015, Louise and her brother participated in their first overseas engagement. They accompanied their parents on a trip to South Africa.

In 2011, at age 7, Lady Louise was a bridesmaid at the wedding of Prince William and Catherine Middleton.

In June 2008, to recognise a visit by her father to the Canadian province of Manitoba, the Lieutenant Governor of Manitoba-in-Council named a lake in the north of the province after Lady Louise.

Born with esotropia, Lady Louise underwent an operation in an unsuccessful attempt to correct the problem in January 2006. She had further treatment in late 2013 that corrected her vision.

She was baptised in the Private Chapel of Windsor Castle on 24 April 2004 by David Conner, the Dean of Windsor and her godparents were Lady Sarah Chatto, Lord Ivar Mountbatten, Lady Alexandra Etherington, Francesca Schwarzenbach and Rupert Elliott. Louise was the last child to wear the original royal christening gown.

Lady Louise Alice Elizabeth Mary Mountbatten-Windsor (born 8 November 2003) is the elder child and only daughter of Prince Edward, Earl of Wessex, and Sophie, Countess of Wessex. She is the youngest granddaughter of Queen Elizabeth II and Prince Philip, Duke of Edinburgh. She is 13th in the line of succession to the British throne.

Lady Louise was born prematurely on 8 November 2003 at 23:32 GMT at Frimley Park Hospital in Frimley, Surrey after her mother was rushed there by ambulance from the Wessex home at Bagshot Park, Surrey; Prince Edward was not present for the birth because he was in Mauritius and because it came so suddenly. Lady Louise was delivered via emergency Caesarean section due to placental abruption, which caused severe blood loss to both child and mother. Louise was transferred to a neo-natal unit in St George's Hospital, Tooting, London, as a precaution. Meanwhile, her mother remained at Frimley Park until she was well enough to be discharged, on 23 November 2003. Lady Louise's name was announced on 27 November.

She is styled as "Lady Louise Windsor", although letters patent issued in 1917, and still in force, assign a princely status and the style of Royal Highness to all children of a monarch's sons. Consequently Lady Louise is entitled to the style and title of "Her Royal Highness Princess Louise of Wessex". However, when her parents married, the Queen, via a Buckingham Palace press release, announced that their children would be styled as the children of an earl, rather than as prince or princess. Thus, court communications refer to her as Lady Louise Windsor.
