Margaret of Burgundy

Margaret of York (1446-1503) was the sister of Edward IV of England and wife of Charles the Bold, Duke of Burgundy. Following the death of her brothers, Edward IV and Richard III of England, Margaret became a staunch supporter of anyone who challenged Henry VII's hold on the throne of England, including Lambert Simnel and Perkin Warbeck. Although Warbeck was undoubtedly an impostor, Margaret acknowledged him as her nephew, Richard, Duke of York.
