Alexander Stewart, 4th High Steward of Scotland

From Freepedia

Alexander Stewart (c.1214-c.1283) was the hereditary High Steward of Scotland from c.1241 until his death. He was a member of the House of Stewart (later known as Stuart).

Alexander was the great-grandfather of King Robert II, the first Stewart to be King of Scots, and thus an ancestor of all subsequent Scottish monarchs (and the current British royal family).

Alexander was also the direct male-line ancestor, through his second son, of Henry Stuart, Lord Darnley.
