They kept trysts at his studio at 20 Pimlico Road, then, as the relationship deepened and their anxiety about being discovered increased, he rented a ground-floor room at 59 Rotherhithe Street, Bermondsey, overlooking the river. They married on Friday 6 May, 1960. Armstrong-Jones was given the title Lord Snowdon, to reflect his Welsh ancestry, in October 1961. On 3 November 1961, Margaret gave birth to their first child, David Albert Charles, Viscount Linley. His sister, Lady Sarah Armstrong-Jones, was born at Kensington Palace on 1 May 1964.
