Who is Norton in The Crown? Everything you need to know about Norton Knatchbull 

Norton Knatchbull is the husband of Penny Knatchbull who was a close friend of the late Prince Philip since they first met in the 1970s. Though the Knatchbull’s royal connections go even deeper than that as Norton is not only the Duke of Edinburgh’s godson but his cousin. 

Norton Knatchbull, 3rd Earl Mountbatten of Burma, is the grandson of the late Lord Mountbatten via his mother Patricia Knatchbull, 2nd Countess Mountbatten of Burma (née Mountbatten). Played in the show by Charles Dance, Lord Mountbatten’s position as King Charles’ mentor was showcased and he was Prince Philip’s uncle. This makes Norton Knatchbull and Prince Philip first cousins, once removed.

Norton was born in 1947 - the same year that the Queen married Prince Philip - and the Duke of Edinburgh attended his christening. Norton was educated at Gordonstoun in Scotland where he is understood to have been close with the then-Prince Charles who also attended the boarding school.

Prince Charles was best man at his wedding to Penelope Eastwood in 1979 at Romsey Abbey in Hampshire, which Prince Philip also attended. This special day had been postponed, however, following the assassination of Lord Mountbatten. Norton’s paternal grandmother, Dowager Lady Brabourne and Norton’s younger brother Nicholas Knatchbull also died in the bombing.

After marrying, Norton Knatchbull and Penny Knatchbull settled at the family home, Broadlands in Hampshire, where the Queen and Prince Philip spent their honeymoon. At this time (and at the time of The Crown season 5) they were known as Lord and Lady Romsey and upon the death of Norton’s father in 2005, they became Lord and Lady Brabourne after he inherited the title Baron Brabourne. 

Norton and Penny had three children - Nicholas Knatchbull, now Lord Brabourne, Lady Alexandra Hooper and the late Lady Leonora Knatchbull who passed away in 1991. After many years, Norton and Penny’s marriage went through a difficult time in 2010 when he is understood to have left his wife for a fashion designer based in the Bahamas.

In 2014 Norton Knatchbull reportedly returned to the UK and moved into a converted barn on the family estate. Since then, the couple are said to have reconciled and now once more live together at Broadlands. When his mother died in 2017, Norton became 3rd Earl Mountbatten of Burma.

The tragic true story of Norton and Penny's daughter, Leonora Knatchbull  

In the first episode of The Crown season 5, viewers are introduced to Norton and Penny Knatchbull’s daughter Leonora. She was Princess Diana’s goddaughter and is shown to be very ill in the show which is an unbelievably tragic real-life story. Leonora Knatchbull was Earl and Countess Mountbatten (then Lord and Lady Romsey)’s daughter and she was diagnosed with kidney cancer. 

At just five years old Leonora passed away and it’s understood that Prince Philip and the Queen were a huge source of support for her grieving parents.

As reported by The Sun (opens in new tab), a source suggested that the Duke of Edinburgh especially helped Penny Knatchbull, claiming, “He was a tremendous support during a time of unimaginable grief.”

Following Leonora’s death, Norton and Penny Knatchbull set up the Leonora Children’s Cancer Fund charity. This is since understood to have been merged with The Edwina Mountbatten Trust to become The Edwina Mountbatten and Leonora Children’s Foundation which aims to provide relief for sick or distressed children across the world, to promote nurses, to support them caring for children suffering from cancer and further research into pediatric cancer.
