Please answer the following question: Information: - The title of High Steward or Great Steward was given in the 12th century to Walter Fitzalan, whose descendants became the House of Stewart. In 1371, the last High Steward inherited the throne, and thereafter the title of High Steward of Scotland has been held as a subsidiary title to that of Baron of Renfrew & Duke of Rothesay, held by the heir-apparent. Thus, currently, The Prince of Wales is High Steward of Scotland, sometimes known as the Prince and Great Steward of Scotland. - Marjorie Bruce or Marjorie de Brus (1296/7 2 March 1316) was the eldest daughter of Robert the Bruce, King of Scots by his first wife, Isabella of Mar. Her marriage to Walter, High Steward of Scotland gave rise to the House of Stewart. Her son was the first Stewart monarch, King Robert II of Scotland. Her widowed father later married Elizabeth de Burgh. - Isabella of Mar (modern Scottish Gaelic: "Iseabail") (c. 1277 12 December 1296) was the first wife of Robert the Bruce and the grandmother of Robert II of Scotland, founder of the royal House of Stuart. She died before Robert was crowned King of Scots, and never became the Queen. - Walter Stewart ( c. 1296 -- 9 April 1327 at Bathgate Castle ) was the 6th hereditary High Steward of Scotland . He was also the father of King Robert II of Scotland . - Duke of Rothesay is a title of the heir apparent to the British throne, currently Prince Charles. It was a title of the heir apparent to the throne of the Kingdom of Scotland before 1707, of the Kingdom of Great Britain from 1707 to 1801, and now of the United Kingdom of Great Britain and Northern Ireland. It is the title mandated for use by the heir apparent when in Scotland, in preference to the titles "Duke of Cornwall" (which also belongs to the eldest living son of the monarch, when and only when he is also heir apparent, by right) and "Prince of Wales" (traditionally granted to the heir apparent), which are used in the rest of the United Kingdom and overseas. The Duke of Rothesay also holds other Scottish titles, including those of Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland. The title is named after Rothesay on the Isle of Bute, Argyll and Bute, but is not associated with any legal entity or landed property, unlike the Duchy of Cornwall. - Robert II (2 March 1316 19 April 1390) reigned as King of Scots from 1371 to his death as the first monarch of the House of Stewart. He was the son of Walter Stewart, 6th High Steward of Scotland and of Marjorie Bruce, daughter of Robert the Bruce and of his first wife Isabella of Mar.
