Richard of York was born about 20 July 1385 at Conisbrough Castle, Yorkshire, the second son of Edmund of Langley, 1st Duke of York, and his first wife, Isabella of Castille. On his father's side, he was the grandson of King Edward III and Philippa of Hainault, and on his mother's side, the grandson of Peter the Cruel, King of Castile and Leon, and his favourite mistress, María de Padilla (died 1361). His godfather was King Richard II. There is no record of his birth or baptism and others put his birth in about 1375. Richard II was at York on 20 July 1385, and in 1375 the future king was only eight years old; it was unlikely he would have been a godfather at that age, and with his father still alive.
