Rachel Wriothesley, born in 1636, was second daughter of Thomas Wriothesley, Earl of Southampton, by his first wife, Rachel de Ruvigny, of an ancient Huguenot family. Her mother died during her infancy. An elder sister, Lady Elizabeth, married Edward Noel, son of Viscount Campden, afterwards Earl of Gainsborough. Lord Southampton married twice after his first wife's death, but he had only one surviving daughter by his second marriage, who being heiress of Sir Francis Leigh, afterwards Earl of Winchester, the whole of the Southampton property was left to the children of his first marriage, who thus became considerable heiresses. Lady Rachel, when yet young, married Francis, Lord Vaughan, eldest son of the Earl of Carberry, but it was an alliance rather of acceptance than of choice on either side, and the early death of Lord Vaughan left her free to marry again. All we know is that she possessed the love and attachment of her husband and the respect of his family. They had one child who died in infancy. In 1667, on the death of her father, she inherited the estates of Stratton, but she passed most of her time with her beloved sister, Lady Elizabeth Noel, at Tichfield, in Hampshire. There she became engaged to Mr. Russell, younger son of the Earl of Bedford. They were married in 1669, but she still retained the name of Vaughan till in 1678, on the death of his elder brother Francis, William succeeded to the courtesy title of Lord Russell, when she assumed that of Lady Russell.
