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.

He was succeeded by his son, Edward II, who subsequently held Marjorie captive in a convent for about seven more years.

She was freed in October 1314, in exchange for Humphrey de Bohun, 4th Earl of Hereford captured after the Battle of Bannockburn.

[5] Upon the liberation of Elizabeth de Burgh and Marjorie from their long captivity in England, Walter Stewart, 6th High Steward of Scotland, was sent to receive them at the Anglo-Scottish border and conduct them back to the Scottish court.

[3] The traditional story is that two years later, on 2 March 1316, Marjorie was riding in Gallowhill, Paisley, Renfrewshire while heavily pregnant.

[10] Following the same October 1317 tradition, the Renfrewshire historian Crawford recorded circa 1710 that local tradition reported she was "riding betwixt Pasly and the Castle of Renfrew, then the principal Residence of the Great Stewart of Scotland, her Husband, she was thrown from her Horse, and by the fall suffered a Dislocation of the Vertebrae of her Neck; she, being pregnant, fell in Labour (of King Robert II.)

the child or Faetus, as they report, was a Cesar[ian]: The Operation being by an unskilful Hand, his Eye was touch'd by the Instrument, which afterwards proved incurable, from which he was called King Bleareie [ie.

"[11] This tradition appears to conflate the dates and facts from other known sources, however authentic references to the sight affliction occurring in infancy, and the related nickname, are lacking.

Her descendants include the House of Stewart (now styled Stuart) and all their successors on the throne of Scotland, England and the United Kingdom.

The young adult novel Girl in a Cage, by Jane Yolen and Robert J. Harris, features Marjorie Bruce as its protagonist.

[13] In the historical action drama film Outlaw King (2018), Marjorie is featured as a minor character during the First War of Scottish Independence.
