In the south aisle of St Margaret's church Westminster is a large monument to Mary, wife of Edward Sutton, Lord Dudley, who died in 1600. It shows a recumbent effigy of Mary in a red cloak trimmed with fur, wearing a ruff and headdress, with a lion at her feet. It is thought to be from the Cure sculpture workshop. it has been moved several times. In 1708 it was to the north of the altar. Beside the tomb is a praying figure of her second husband Richard Mompesson of Wiltshire who put up the monument. Originally there was a faldstool with a book in front of him. This figure could be by sculptor Isaac James. Above the tomb is a shield of arms. The inscription reads:
