Anne, Countess of Strafford, was the second daughter of John Campbell, 2nd Duke of Argyll and 1st Duke of Greenwich, and his second wife Jane, daughter of Thomas Warburton. On 28 April 1741 she married William Wentworth, 4th Earl of Strafford, of Wentworth Castle. A celebrated society beauty, her appearance was warmly praised by Horace Walpole in the poem The Beauties, written in 1746. She was a recipient of a celebrated series of letters from her sister, Lady Mary Coke, which are a key source of social information of the time. A full-length portrait of the sitter in peeress's robes, painted by Ramsay in 1743, is in the Hunterian Art Gallery, Glasgow.
