On 9 March 1960, following Princess Margaret’s engagement to photographer Antony Armstrong-Jones earlier in the year, a formal announcement was issued from Clarence House: ‘The marriage of Her Royal Highness The Princess Margaret with Mr Antony Armstrong-Jones will be solemnised at Westminster Abbey on the morning of Friday, May 6th, 1960, at 11.30 o’clock.’
This was the first royal wedding to be televised. After the ceremony the couple boarded the royal yacht Britannia to embark upon their honeymoon in the Caribbean.
The couple moved into Apartment 10, Kensington Palace before moving to Princess Margaret's former apartment in early 1963 where they made their family home.
On 3 November 1961, Princess Margaret and Lord Snowdon had their first child, a son born in Clarence House, and christened David Armstrong-Jones, Viscount Linley.
Their second child, a daughter, Lady Sarah Frances Elizabeth, was born at Kensington Palace on 1 May 1964.
