Richard married Anne Neville, whose father had once been a friend of the family. Richard and Anne had known each other since they were children, but Anne had been taken to France, where she had married the Prince of Wales, the son of Henry VI. When the Prince of Wales was killed in battle, Anne became a widow, and soon she was married to Richard, even though he had been her husband's enemy. Richard and Anne lived at Middleham Castle in North Yorkshire. They had one son, who was named Edward after Richard's brother, King Edward. Richard quarrelled frequently with his brother George, who was married to Anne's sister, Isabel. King Edward became so angry that he put George in prison, where he died.
