King Charles’s cousin, Lady Sarah Chatto, had a reason to celebrate with her husband, Daniel, and their family on Sunday.
The couple’s youngest son, Arthur Chatto, turned 24 on 5th February 2023.
Arthur used to post regularly on his now-defunct Instagram page, but deleted his account in 2021, after joining the Marines.
Lady Sarah Chatto and Daniel also have an older son, Samuel, 26, and both he and Arthur attended Eton College and the University of Edinburgh.
While they lead fairly private lives, Sam and Arthur have in the past attended public events with the royal family, including Christmas at Sandringham and Prince Harry and Meghan Markle’s wedding in 2018.
Sam, who was born in 1996, is Princess Margaret’s eldest grandchild. She passed away in 2002 at the age of 71.
Arthur was a page of honour to his great-aunt, the late Queen Elizabeth II, from 2009 to 2015.
The brothers are 28th and 29th in line to the throne respectively behind their mother and their cousins, Charles Armstrong-Jones, Viscount Linley, and Lady Margarita Armstrong-Jones.
