Who was Leonora Knatchbull and who plays her in The Crown?

The daughter-in-law to Philip's cousin, Penny must face the loss of her youngest daughter Leonora, and Philip helps her to channel her grief into new outlets – one of which is quite inspiring.

However, who plays Leonora Knatchbull in The Crown and what happened to her in real life?

Who was Leonora Knatchbull?

Leonora Knatchbull was the third and youngest child of Norton Knatchbull, Lord Romsey, and Penelope Knatchbull, Lady Romsey.

Norton is the son of Patricia Edwina Victoria Knatchbull, 2nd Countess Mountbatten of Burma and John Knatchbull, Baron Brabourne. Through his mother, Norton is the grandson of the late Louis Mountbatten, Earl Mountbatten of Burma and is therefore the cousin of the late Prince Philip, Duke of Edinburgh.

Upon his mother's death in 2017, Norton became Earl Mountbatten of Burma and Penelope became Countess Mountbatten of Burma.

Leonora Louise Marie Elizabeth Knatchbull was born on 25th June 1986 and played with a number of aristocratic and royal children, moving in similar circles to the royal family.

She was pictured on Buckingham Palace's balcony during the Trooping the Colour in 1991, standing in front of Diana, Princess of Wales in red.

Sadly, the much-loved Leonora had a tragically short life and became ill with kidney cancer, dying at the age of five at St. Bartholomew's Hospital in London on 22nd October 1991.

Leonora was buried at her family's estate of Broadlands near the town of Romsey.

In 1994, Norton and Penelope Knatchbull set up Leonora Children's Cancer Fund in memory of Leonora.

The Duke of Edinburgh attended a reception to promote the charity in 1994.
