A Woman, called the Duchess of Suffolk

The sitter is identified in the Cartwright inventory as 'ye Duchiss of Suffouck'. This has been taken to refer to Frances Brandon, Duchess of Suffolk (1517-59), the mother of Lady Jane Grey. However, the costume appears to date from after Frances Brandon's death. Jeffree suggests that she may be Catherine Willoughby de Eresby (1519-80), fourth wife of Charles Brandon, Duke of Suffolk.
