16th century portrait of a lady in the collection of Audley End House, labelled as Jane Grey, copy of the original at Syon House. Based on a portrait type identified as Lady Katherine Grey or Elizabeth I, it is believed that the Syon Portrait was created by William Seymour, 2nd Duke of Somerset, with the help of his grandfather, Lady Katherine Grey's widower, who had also known Lady Jane Grey, tweaking the portrait type into a genuine resemblance of her.
