Marjorie Bruce or Marjorie de Brus (c. 12961316 or 1317) was the eldest daughter of Robert the Bruce, King of Scots, and the only child born of his first marriage with Isabella of Mar. Marjorie's 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. Early life Her mother, Isabella, was a noblewoman from the Clan Mar. Marjorie was named after her father's mother, Marjorie, Countess of Carrick. Soon after giving birth to Marjorie, at the age of 19, Isabella died. Marjorie's father was at that time the Earl of Carrick. According to legend, Marjorie's parents had been very much in love, and Robert the Bruce did not remarry until 1302 (six years after his first wife's death), to a courtier named Elizabeth de Burgh. On 27 March 1306, her father was crowned King of Scots at Scone, Perthshire, and Marjorie, then 10 years old, became a Princess of Scotland. Imprisonment Three months after the coronation, in June, 1306, her father was defeated at the Battle of Methven.

This is due to the fact that Edward I needed the support of her father, the powerful Earl of Ulster. Marjorie's aunt, Mary Bruce, and the Countess of Buchan were imprisoned in wooden cages, exposed to public view, at Roxburgh Castle and Berwick Castle, respectively. For the next four years, Elizabeth, Christina, Mary, and Isabella endured solitary confinement. The latter two experienced daily public humiliation. A cage was built for Marjorie, who was around the age of 12, at the Tower of London, but Edward I reconsidered. He instead sent her to the Gilbertine convent in Watton. Christopher Seton, Christina's husband, was executed. Edward I died on 7 July 1307. He was succeeded by his son, Edward II, who subsequently
