For many years the billionaire Duke of Westminster was dubbed the UK's most eligible bachelor.
But he's now officially off the market after tying the knot with his new wife Olivia, the new Duchess of Westminster, at Chester Cathedral last week. The pair married in a grand affair with over 400 guests including Prince William and Princess Eugenie. However, there are still several aristocratic young men who stand to inherit fancy titles and vast fortunes that still appear not to have been snapped up...
Louis Spencer, Viscount Althorp
One of them is Louis Spencer, a nephew of Princess Diana and a cousin of Princes William and Harry. He is the eldest son of Diana's brother Earl Spencer and his first wife, Victoria Lockwood. He has three glamorous older sisters - Lady Kitty, Lady Amelia and Lady Eliza Spencer - and has also been dubbed 'the world's most eligible bachelor' as well as 'Prince Harry lite'.
Louis, 30, is said to be 'super private' but has a budding acting career. He previously graduated with a First from ArtsEd, an independent performing arts school based in Chiswick, and signed to talent agency Tavistock Wood. He is listed on their client list as Louis John Lyons and joins other famous faces the agency represents, which include Lily James, Rebel Wilson and Dustin Hoffman.
One day he will inherit the family's 13,500-acre Althorp estate in Northamptonshire as his father, Earl Spencer's heir apparent - despite having three older sisters. Oldest sister Kitty previously said: "We've grown up understanding that it's Louis to inherit, and Louis will do an incredible job."
Meghan Markle 'to unleash her own memoirs' as Prince Harry's drops next weekCharles Armstrong-Jones, Viscount Linley
Meanwhile, one low-key member of the Royal Family who is still seemingly on the market is Charles Armstrong-Jones. He is the son of Earl Snowdon, making him a grandson of Princess Margaret, the only one to have a title and a great-nephew of the late Queen. He is the heir to the Earldom of Snowdon and is currently 26th in line to the throne.
Like his older relatives Princes William and Harry, he went to Eton College and was in the same year as his cousin Arthur Chatto, the son of his aunt Lady Sarah Chatto and her husband Daniel. The 24-year-old later went on to study at Loughborough University and now works as a musician.
His sister Margarita previously told Tatler: "He is very into his orchestral music. He is self-taught [and he] can sing, play the piano and the guitar. Somehow he combines it all together – including online choirs – on his laptop into one piece of music."
Cassius Taylor
Another royal you may not have heard of - but is seemingly romantically unattached - is 49th in line to the throne Cassius Taylor.
The 27-year-old is the son of Lady Helen Taylor and her husband Timothy and is a grandson of the Duke of Kent, a cousin of the late Queen. He mainly grew up away from the spotlight but would make fleeting appearances at the likes of Trooping the Colour when all royals piled onto the balcony in previous years.
He grew up alongside his older brother Columbus and younger sisters Eloise and Estella. After attending the private Wellington College in Berkshire he got an art management degree at Goldsmiths University. Now he is known as a DJ as well as a brand ambassador for the clothing label Stone Island, and documents his life on Instagram, which includes snaps of him alongside his cousin Lady Amelia Windsor.
He was previously dubbed one of the UK's most eligible bachelors by Tatler and told the magazine: "I always knew I'd end up in the creative industries in some capacity, due to my upbringing, similar to everyone in my family."
George Percy, Earl Percy
Although not a royal but extremely close to them, George Percy is still seemingly unaccounted for.
The 40-year-old, who was previously a page of honour for the late Queen stands to inherit the title of Duke of Northumberland as well as a 100,000-acre estate, a £509million fortune and Alnwick Castle. The Old Etonian went to Edinburgh University, where he was a flatmate of the Princess of Waleses' sister Pippa and appears to keep his life very much private.
Charlie Gordon-Lennox, Earl of March and Kinrara
He may only be 29 but Charlie Gordon-Lennox, also known as the Earl of March and Kinrara, has already had a high-flying life.
Harry and Meghan convinced 'royals were against them' after New Year photo snubAfter studying in Oxford he is currently living in New York and most recently set up a menswear brand called Understated.Era. He is the heir to the title the Duke of Richmond and the stunning 12,000-acre Goodwood estate in Sussex, home to Goodwood racecourse and the Goodwood Aerodrome.
He previously told Magneto magazine: "I never realised how different it was until I was ten or 11. I'd go to my mates' houses because they were allowed to go on their computer for longer than I was, and they would come to my house because it was better for hide and seek. And then I started to realise, oh, wait, this is a bit weird."
