Princess Diana statue unveiling: Princes Harry and William reunited with her ...

The McCorquodales 

Sarah and Neil McCorquodale

Lady Sarah McCorquodale, 63, is the eldest of the Spencer children. She dated Prince Charles in 1977 and introduced the royal to her youngest sister. She married Neil McCorquodale, a farmer and former officer with the Coldstream Guards, in May 1980. 

The couple have three children and two grandchildren.

Emily McCorquodale

Emily McCorquodale, 34, is the eldest of the McCorquodale brood. In 2003, aged 19, she was diagnosed with cancer while studying at Leeds Metropolitan University but was later given the all-clear. 

In 2012 she married husband James Hutt, whom she met on a blind date, in a ceremony in Lincolnshire, which was attended by Prince Harry and the Duke and Duchess of Cambridge. The couple have two children, Isabella, three, and Henry, two.

George McCorquodale

Like Harry, George McCorquodale, 33, inherited the ginger Spencer curls. He is said to enjoy a close relationship with his cousins after joining them for family holidays on Necker, Sir Richard Branson’s private island. 

Prince Harry was guest of honour when George married Bianca Moore, at Netherwood in KwaZulu-Nata, South Africa, in August 2016. 

Celia McCorquodale

Celia, believed to be 28, made headlines in 2012 with an album of photos that showed her partying with friends at Leeds University. 

Celia will soon be following her cousin down the aisle. She announced her engagement to George Woodhouse on 13 November 2017. 

The Fellowes

Lady Jane and Lord Robert Fellowes

Lady Jane Fellowes, 61, is Diana's elder sister. One of her godparents is the Queen's cousin, the Duke of Kent.

She is married to Robert Fellowes, a former Private Secretary to the Queen and first cousin of Ronald Ferguson, the father of Sarah, Duchess of York.

In June 1999, Robert Fellowes was granted a life peerage as Baron Fellowes, of Shotesham in the County of Norfolk, after first being knighted as Sir Robert Fellowes. The couple have three children and four grandchildren.  

Laura Fellowes

Laura, 37, is very close to William and Harry and is one of Princess Charlotte's godparents.  

She married equity analyst Nick Pettman in 2009 in Snettisham, west Norfolk, where her parents live in an old rectory. William and Kate were both guests.

Laura writes fiction under the name Mave Fellowes — her nickname is Mavis — and has sons.

Alexander Fellowes

Alexander — known as Beetle to friends — is a 35-year-old investment banker. He married Alexandra Finlay at the Chapel of St Mary Undercroft in the Palace of Westminster in September 2013. Prince Harry attended the wedding.  

Alexander and Alexandra have two children, Robert, three, named after his grandfather, and 18-month-old Rose.  

Eleanor Fellowes

Eleanor Fellowes, 32, keeps a relatively low profile and is rarely seen at public events. She is believed to work as a probation officer and has published articles on issues relating to her profession. 

The Spencers

Charles Spencer and Karen Gordon

Charles, 53, the 9th Earl Spencer, is the most high profile of Princess Diana's siblings. In his eulogy at Diana's funeral, the journalist and broadcaster criticised the Royal Family and the Press on their treatment of his sister. 

In 1989 Spencer, then known by the courtesy title of Viscount Althorp, married his first wife, Victoria Lockwood, in Great Brington, Northamptonshire. The couple, who divorced in 1997, had three daughters and a son.

In December 2001 he married Caroline Freud, former wife of Matthew Freud. The couple had two children together, Edmund and Caroline. They divorced in 2007. 

Spencer married his current wife, Canadian-born philanthropist Karen Gordon, in June 2011 at the family seat of Althorp House. They have one child together, Lady Charlotte Diana Spencer, named after his sister. 

The couple reside at the Spencer ancestral seat, Althorp House, which he inherited on his father's death in 1992.

Lady Kitty Spencer

Lady Kitty Spencer, 27, has forged a successful career as a model, most notably appearing in campaigns for Italian fashion house Dolce & Gabbana. 

The socialite, who is signed with Kate Moss's former modelling agency Storm, is a regular fixture at the world's hottest parties and is sure to cause a stir at the Royal Wedding. 

She is regarded as one of the most eligible young women on London's social scene, having split from her property tycoon boyfriend at the start of the summer. Lady Kitty grew up in South Africa and is now based in Fulham.

Lady Eliza and Lady Amelia Spencer   

Twins Lady Eliza and Lady Amelia, 25, share their elder sister's good looks but keep a much lower profile. 

Like their sister, the twins were raised in South Africa and attended university in Cape Town.

In 2011 Lady Amelia appeared in a South African court accused of assaulting a man on crutches in McDonald's. She was cleared of all charges.

Louis Spencer 

Louis, 24, is the fourth child and eldest son of Earl Spencer and will therefore inherit his father's estates and title ahead of his elder sisters. 

He studied at Diocesan College in Cape Town and later enrolled at the University of Edinburgh.

Edmund and Caroline Spencer

The Vanity Fair report makes no mention of Edmund and Caroline Spencer, Charles' children from his second marriage, receiving an invite to the royal wedding. 

As Edmund, 14, and Caroline, 12, are still young, they perhaps wouldn't attend the late-night after-party. 

Lady Charlotte Spencer

Lady Charlotte Diana, five, is Earl Spencer's youngest child and his only one with third wife Karen. 

Like her half-siblings Edmund and Caroline, Lady Charlotte is not named in the Vanity Fair report and would be unlikely to receive a late-night party invite because of her age.
