From the French version of the surname Stewart. This form was introduced to Scotland in the 16th century by Mary Stuart, Queen of Scots, who was brought up in France. The surname originated as an occupational or status name for someone who served as a steward in a manor or royal household. The Scottish royal family of this name are traditionally supposed to be descended from a family who were hereditary stewards in Brittany before the Conquest. Use as a given name originated in Scotland, but is now widespread throughout the English-speaking world.
