Who Are Princess Margaret's Children? Get to Know Her Under-the-Radar Royal Offspring

David founded the furniture company Linley in 1985. He married Serena Alleyne Stanhope at St. Margaret's church in Westminster in October 1993, and they have two children together: son Charles Patrick Inigo Armstrong-Jones, Viscount Linley, born in 1999, and daughter Lady Margarita Elizabeth Rose Alleyne Armstrong-Jones, born in 2002 (just three months after Princess Margaret's death). You might remember a young Lady Margarita as one of Prince William and Kate Middleton's bridesmaids back in 2011.

In February 2019, it was reported that the Earl of Snowdon is working on a biography of his late mother that will include her correspondence and information from historians and the Royal Archives at Windsor Castle.
