Brief Biography

from: Children of Robert Bruce: Blog, by Laura Vosika, author of the "Blue Bells Trilogy"

Most sources agree Marjory was born in December of 1296, the same month Longshanks invaded Scotland and took Berwick. As an author, I could hardly write better foreshadowing for the life Marjory would lead. In June 1306, at the age of 9, she was captured at St. Duthac in Tain, north of Inverness, while trying to escape to safety in Orkney. It is all too easy to imagine the terror of a 9 year old girl, separated from her father, who she knows is fighting not just for his kingdom, but for his life, seeking safety in a church with her aunts and step-mother, and seeing armed men storm into what should have been a place of refuge and safety. It is easy to imagine the terror of wondering what had become of her Uncle Nigel who had tried to protect them, still under attack back at Kildrummy; or what would become of Sir John of Atholl, who had whisked them away from Kildrummy for safety, or her aunts and step-mother.

We know that two of the women captured in the church that day–Isobel MacDuff and Mary Bruce, Marjory’s aunt–would spend years living in cages hung on castle walls. Edward I had a similar cage built for Marjory at the Tower of London, but in a rare moment of softness, reconsidered and instead ordered her held in solitary confinement in the nunnery at Watton. There, the young Marjory lived, virtually alone, for 8 years. She was released after Bannockburn in 1314, when she was still 17, in exchange for English prisoners held by the Scots.

The following year, she married Walter, the 6th High Steward of Scotland, who was only 22 himself at the time, but one of the heroes of Bannockburn. She very quickly became pregnant. The following March, she rode her horse in the late stages pregnancy, fell when it reared, and delivered the future Robert II by c-section on March 2, 1316, according to Electric Scotland. (link6)

She died at the age of barely 19, having spent close to half her life in near-solitary confinement. It hardly gets more tragic than this.

-------------------- Robert Bruce, King of Scotland, was born the 11th of July 1274, and died June 7, 1329. He married first Isabella, eldest daughter of Donald, tenth Earl of Marr. Their daughter, Marjory, Princess Royal of Scotland, fell into the hands of the English 1306, and was detained a prisoner in charge of Henry Percy till 1314, when she was conducted to Scotland by Walter, the sixth high steward of Scotland, to whom she was married in 1315. She died in March, 1316. Her husband, Walter, born in 1294, brought a noble body of men to the aid of Bruce. In the battle of Bannockburn he and his cousin, Sir James Douglas, commanded the Third division. The same year he was appointed to receive, on the borders, the Queen of King Robert, Marjory, his daughter, and other illustrious Scottish prisoners. On that occasion he formed an attachment for the Princess. He died April 9, 1326. "Had he lived," says an old writer, "he might have equaled Randolph and Douglas; but his course of glory was short." The only child of the Princess Marjory was Robert Stuart, King of Scotland, born March 2, 1316.
