Marjorie Bruce, although her father was Robert “the” Bruce, she didn’t exactly lead a cushy life as the daughter of a king. Kept in a cage by Edward I for over a year, sent to a nunnery by Edward II for 8 years- and finally set free in 1314… only to be given to Walter Stewart as a “reward” at the age of 18.
A year later she went into premature labor after a riding accident and gave birth to a son, Robert II of Scotland. Her last words were “He’s a laddie; I ken he’s a laddie; he will be King.” She died a few hours later. Her descendants include the House of Stuart and all their successors on the throne of Scotland, Great Britain and the United Kingdom.
