The sitter was the daughter of George Brydges, 6th Baron Chandos (1620–55) and his second wife Lady Jane Savage. She married, as his first wife, Adam Loftus (1647–91), the second son of Sir Arthur Loftus of Rathfarnham, County Dublin and his wife, Lady Dorothy Boyle, daughter of the 1st Earl of Cork. A member of the Privy Council of Ireland and Ranger of Phoenix Park, Loftus was created Baron Rathfarnham and Viscount Lisburne in 1686 by King James II. Little is known about Lady Lisburne's life, however she was clearly considered a celebrated beauty as a number of versions of this portrait exist. The prime portrait by Lely was in the celebrated collection of Robert Walpole, 1st Earl of Orford (1676–1745) at Houghton Hall in Norfolk.
