Stewart or Stuart?
The House of Stuart, originally Stewart, was a royal house of Scotland, England, Ireland and later Great Britain. The family name comes from the office of High Steward of Scotland, which had been held by the family progenitor Walter fitz Alan (c. 1150). The name Stewart and variations had become established as a family name by the time of his grandson Walter Stewart. The first monarch of the Stewart line was Robert II, whose male-line descendants were kings and queens in Scotland from 1371, and of England and Great Britain from 1603, until 1714. Mary, Queen of Scots, was brought up in France where she adopted the French spelling of the name Stuart.
