Anne Neville was the daughter of Warwick the Kingmaker and the queen consort of Richard III. Her father was Richard Neville, 16th Earl of Warwick, one of the most powerful Yorkist figures in the Wars of the Roses.
Anne first married Edward of Westminster, the Lancastrian Prince of Wales, in 1470. After his death at the Battle of Tewkesbury in 1471, she married Richard, Duke of Gloucester, probably in 1472. He became Richard III in 1483, making Anne queen consort.
The main mix-up is with Cecily Neville, Richard III’s mother, not his wife. Anne’s elder sister, Isabel Neville, married George, Duke of Clarence, another brother of Edward IV and Richard III. Anne and Richard had one surviving child, Edward of Middleham, who died young in 1484. Anne died in March 1485, five months before Richard was defeated at Bosworth.
