Richard was the oldest son and third child of the countess and earl of Salisbury. Joan, whose birthdate is unknown, seems to have been the oldest child, followed by Cecily. There is a possibility, given that 22 November is St Cecelia’s Day, that Richard and Cecily were twins but, given that Salisbury’s younger sister was also named Cecily, this is pure speculation. His mother was 21 and his father 28 at the time of his birth. Some sources place his birth at Bisham, a property of his mother’s, or somewhere in ‘Wessex’, though I’ve seen nothing more specific than this.
Richard married Anne Beauchamp in 1436 and became earl of Warwick in her right in 1449. They had two children, Isobel (born 1451) and Anne (born 1456). Warwick was killed at the battle of Barnet on 14 April 1471. He was 42 years old.
