Duchess of Rothesay
Duchess of Rothesay is a Scottish courtesy title. It is held by the wife of the duke of Rothesay since the first duke in 1398. The Act of Union of 1707 united the kingdoms of Scotland and England into the Kingdom of Great Britain. Ever since 1603 the title of the Duchess of Rothesay is held by the wife of the Prince of Wales, who was also the Duchess of Cornwall and almost always the Princess of Wales; the title of Duchess of Rothesay is for her use when in Scotland.
Since under current succession law the title of Duke of Rothesay can only be held by an heir-apparent who is also the eldest son of the monarch, no woman has been Duchess of Rothesay in her own right thus far.
