Cecily Neville was an English noblewoman, the wife of Richard, Duke of York (1411–1460), and the mother of two kings of England—Edward IV and Richard III. Cecily Neville was known as "the Rose of Raby", because she was born at Raby Castle in Durham, and "Proud Cis", because of her pride and a temper that went with it, although she was also known for her piety. She herself signed her name "Cecylle".

Richard of York, 3rd Duke of York, also named Richard Plantagenet, was a leading English magnate and claimant to the throne during the Wars of the Roses. He was a member of the ruling House of Plantagenet by virtue of being a direct male-line descendant of Edmund of Langley, King Edward III's fourth surviving son. However, it was through his mother, Anne Mortimer, a descendant of Edward III's second surviving son, Lionel of Antwerp, that Richard inherited his strongest claim to the throne, as the opposing House of Lancaster was descended from John of Gaunt, Duke of Lancaster, the third surviving son of Edward III. He also inherited vast estates and served in various offices of state in Ireland, France and England, a country he ultimately governed as Lord Protector due to the mental instability of King Henry VI.
