Three months after becoming king, Henry married Catherine of Aragon. They tried to have children, as Henry wanted a son who could be the next king. In 1511, she gave birth to a son who they named Henry, but he died seven weeks later. She later gave birth to a girl, the future Queen Mary I. All her other children were stillborn (died before birth). He did have one son (Henry Fitzroy) through a woman he was not married to. This son could not become king.
