Samuel Chatto is celebrating his 28th birthday today (July 28) and although his name might not be familiar to all Royal Family fans he has some pretty impressive roots.

Despite being 29th in line to the throne, he is not a working royal and instead works as an artist producing ceramics in his own studio.

However, back in June he was invited to a prestigious royal event as he joined King Charles to welcome Emperor Naruhito and Empress Masako during the Japanese State Visit.

It might seem like a strange choice but Samuel spent time in Japan last year completing an apprenticeship under professional potter Yagi Akira.

He is the first-born grandson of Princess Margaret, born to Lady Sarah Chatto and her husband Daniel Chatto on July 28, 1996 at London's Portland Hospital.

The Portland is the same hospital where Sarah Ferguson gave birth to Princess Beatrice and Princess Eugenie, cementing his royal connections right from the beginning.

He weighed 7lb 12 oz and was the Queen Mother's seventh great-grandchild, although he and younger brother Arthur, born February 1999, grew up mostly away from the royal spotlight in Kensington.

His grandfather Lord Snowdon, Princess Margaret's former husband, said at the time: "Everyone is absolutely thrilled. He is a splendid baby and very hearty.

"Sarah is very well but very tired. I have spoken to Princess Margaret and she will be going in to see Sarah quite soon."

Samuel's mother Lady Sarah is the daughter of Princess Margaret, while his father Daniel Chatto was an actor before he became an artist.

The family have generally kept away from royal life, with Margaret once saying about her childrern Sarah and her older brother David, Earl of Snowdon: "My children aren't royal, they just happen to have the Queen as an aunt."

Samuel's parents also celebrated their 30th wedding anniversary on July 14 this year, having tied the knot at St Stephen Walbrook Church in London.

Like many male members of the Royal Family, including Princes William and Harry, Samuel and his brother Arthur were sent to Eton College for secondary school.

Samuel went on to study History of Art at the University of Edinburgh, a fitting choice as both his parents have worked as professional artists.

After a three-month stint in commercial art marketing, he channelled his creativity into ceramics.

He has a studio in West Sussex and his work has been displayed in several exhibitions.
