James, both king of Scotland and Stuart king of England before creating the kingdom of Great Britain, was born on 19 June 1566 in Edinburgh Castle. James married Anna, the sister of the Danish king, Christian IV. They had numerous children, three of whom survived infancy: Henry, who died after a short illness in 1612, Charles who was to succeed James, and Elizabeth, who married Frederick, elector of Palatine, and the swiftly deposed King of Bohemia. Romantically she has become known as the Winter Queen. Here’s King James I and VI biography and profile.
