Grey of Groby: Thomas and Richard Grey. Her paternal grandparents were Richard of York, 3rd Duke of York (who claimed the rights of the House of York to the English throne) and Cecily Neville, and her maternal grandparents were Richard Woodville, 1st Earl Rivers, and Jacquetta of Luxembourg, Dowager Duchess of Bedford. The girl was baptized shortly after birth; among her sponsors was the Archbishop of Canterbury and Cardinal Thomas Bourchier. In 1467, the King granted his wife lifelong use of Sheen Palace in Surrey, where the royal nursery was organized: according to tradition, royal offspring were brought up away from London and the court for their safety and health. Here, Mary, along with her older sister Elizabeth (born 11 February 1466), was brought up under the guidance of a governess Lady Margaret Berners (wife of John Bourchier, 1st Baron Berners, great-grandson of King Edward III and a close friend of the Queen Elizabeth's family); Lady Margaret received a salary of 100£ for her services (as of 2013 – 50,000£) per year.
