Crown passes from David II to Robert II

'THE genealogy of the Stewart family, who now acceded to the throne of Scotland, has been the theme of many a fable. But their pedigree has by late antiquaries been distinctly traced to the great Anglo-Norman family of Fitz-Alan in England; no unworthy descent, even for a race of monarchs.  In David I.'s time, Walter Fitz-Alan held the high post of seneschal or steward of the king's household; and the dignity becoming hereditary in the family, what was originally a title was converted into a surname, and employed as such. Walter, the sixth high-steward, fought bravely at Bannockburn, defended Berwick with the most chivalrous courage, and was unanimously thought worthy of the hand of Marjory Bruce, the daughter of the liberator of Scotland; and to their only child, the seventh lord high-steward, often mentioned during the last reign, the crown descended, on the extinction of the Brace's male line in his only son David II.'

On February 22, 1371, King David II of Scotland died.  He was succeeded by the first Stewart king, Robert II.  The text above is from Walter Scott's "Scotland".
