Lady Jane Grey was not descended from the Stewarts, her mother was Frances Brandon, the daughter of Henry VIII's sister Mary. Another sister of Henry VIII, Margaret, did marry into the Stewarts however. Henry's will had excluded her from the succession although she, being older, would have had the better claim.

Jane therefore was only related to the Stewarts through her great aunt.

Jane refused the crown but was told to try it on by her parents and did so out of a sense of filial duty, but she never had a proper coronation.
