This unknown young girl was formerly identified as Bridget Cromwell (1624-81), daughter of Oliver Cromwell. The miniature can be dated to c.1690 on the grounds of costume, and shows a young girl of about ten years of age. It cannot therefore represent any of Oliver Cromwell's daughters. It is a pleasing example of the work of Peter Cross, signed with his interlaced monogram 'PC' on the left. Cross worked as King's Limner from 1678, and he was the most important miniaturist working in London throughout the 1680s and 1690s. He continued to work well into the eighteenth century, when he was able to impart significant details of his skills and experience of miniature painting at first hand to George Vertue. Signed on the left: 'PC' (monogram) and inscribed on the reverse in ink by a nineteenth-century hand: 'Bridget eldest Daughter of Olvier Cromwell married to General Hay...to Gen Charles Fleetwood. She died at Stoke Newington...'
