Cecily Neville, Duchess of York (3 May 1415 – 31 May 1495) was an English noblewoman, the wife of Richard Plantagenet, 3rd Duke of York, 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".
