He was born at Stirling Castle and became Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland when he was born. His father made Alexander Erskine, Earl of Mar, take care of him. He did not let his mother take care of him. This was because James worried that the mother's slight liking for Catholicism might have some effect on the son. Although this made lots of fights between Anna and James, Henry was kept under the care of Mar's family until 1603. This was when James became King of England and his family moved south.
